Photo for the tip: Look at both ends
TIP 1

Look at both ends

Your mind loves the worst case. The worst-case, likely-case exercise forces you to also look at the most likely outcome, which is almost always calmer and more ordinary.

TRY THIS
Draw two columns: “worst” and “likely”.
Photo for the tip: Write the worst case
TIP 2

Write the worst case

Be specific: “I forget my first line, go red and the room goes quiet.” Writing it makes the fear concrete and often less terrifying than the vague dread.

TRY THIS
Write your worst case in two sentences.
Photo for the tip: Rate the worst case
TIP 3

Rate the worst case

Give it a probability from zero to one hundred percent. Your logical side will usually give a lower number than your fear.

TRY THIS
Write a percentage next to your worst case.
Photo for the tip: Write what you would do
TIP 4

Write what you would do

If the worst happened, what would you do next? A concrete answer reveals that you could cope.

TRY THIS
Write your three-step response to the worst case.
Photo for the tip: Write the likely case
TIP 5

Write the likely case

“I feel nervous, I speak a bit fast, and people listen politely.” It may sound dull, which is exactly the point.

TRY THIS
Write your likely case in two sentences.
Photo for the tip: Write the best case
TIP 6

Write the best case

“I smile, the room warms up and someone says well done.” Seeing the best case reminds your brain that good outcomes exist too.

TRY THIS
Write your best case in two sentences.
Photo for the tip: Compare the three
TIP 7

Compare the three

Look at worst, likely and best together. Most people discover that the likely case is far closer to the best case than the worst.

TRY THIS
Read the three versions aloud once.
Photo for the tip: Use real numbers
TIP 8

Use real numbers

If you can, find numbers. How often do speakers faint? How often are interviews cancelled? Real data trims imagination.

TRY THIS
Search one fact related to your fear.
Photo for the tip: Check your history
TIP 9

Check your history

Think of times you faced similar events. How many went badly? Your past record gives your odds.

TRY THIS
Write three similar past events and how they went.
Photo for the tip: Ask someone else
TIP 10

Ask someone else

A trusted friend can give an outside view of how likely your worst case is. Their calm estimate helps recalibrate yours.

TRY THIS
Ask a friend, “How likely do you think this is?”
Photo for the tip: Set the stakes honestly
TIP 11

Set the stakes honestly

Ask what is really at risk: a few minutes of embarrassment, a job, a friendship? Naming the stakes sets a sensible level of worry.

TRY THIS
Write what you really risk in one sentence.
Photo for the tip: Plan for the likely, prepare for the worst
TIP 12

Plan for the likely, prepare for the worst

You do not need to ignore the worst case. You can prepare for it lightly, such as bringing a copy of your notes, and focus on the likely.

TRY THIS
Write one light precaution.
Photo for the tip: Do not stop at the worst
TIP 13

Do not stop at the worst

Many people stop thinking at the awful moment and never imagine what happens next. Keep going: you recover, people forget, life continues.

TRY THIS
Continue the story one hour past the worst moment.
Photo for the tip: Look at the aftermath
TIP 14

Look at the aftermath

Picture the week after your worst case. You will likely be fine, perhaps a little embarrassed, with a story to tell.

TRY THIS
Describe your life a week after the worst case.
Photo for the tip: Add a time lens
TIP 15

Add a time lens

Ask how the worst case will feel in a day, a month, a year. Time shrinks most embarrassments.

TRY THIS
Write your reaction at each time frame.
Photo for the tip: Check for mind reading
TIP 16

Check for mind reading

Your worst case may contain “they will think I am stupid”. Other people’s thoughts are not known. Replace with “they might think anything, and most will not think of me for long”.

TRY THIS
Underline mind-reading phrases in your worst case.
Photo for the tip: Check for all-or-nothing thinking
TIP 17

Check for all-or-nothing thinking

“If I make one mistake, it is a disaster” is a pattern that cognitive therapists, such as Aaron Beck and David Burns, call a thinking error. Spotting it loosens its grip.

TRY THIS
Look for “always”, “never” and “disaster” in your worry.
Photo for the tip: Check for fortune-telling
TIP 18

Check for fortune-telling

You cannot predict the future, even though your mind sounds sure. Label it “fortune-telling” and smile.

TRY THIS
Write “fortune-telling” next to a prediction.
Photo for the tip: Check for emotional reasoning
TIP 19

Check for emotional reasoning

“I feel scared, so it must be dangerous” confuses a feeling with a fact. Feelings tell you about you, not always about the world.

TRY THIS
Write the feeling and then a separate fact.
Photo for the tip: Consider what you would tell a friend
TIP 20

Consider what you would tell a friend

Your advice to a friend with the same worst case would be gentle and realistic. Say that to yourself.

TRY THIS
Write what you would say to a friend.
Photo for the tip: Use the "so what?" question
TIP 21

Use the "so what?" question

“So what if I stumble?” Following the answer often reveals that the consequences are small.

TRY THIS
Ask “So what?” three times in a row.
Photo for the tip: Create a cope plan
TIP 22

Create a cope plan

For each worst-case point, write one coping action. A written plan turns fear into a to-do list.

TRY THIS
Write coping actions beside each point.
Photo for the tip: Practise the plan
TIP 23

Practise the plan

Rehearse your coping actions once. Rehearsed responses are easier under stress.

TRY THIS
Act out your plan in private once.
Photo for the tip: Keep the exercise short
TIP 24

Keep the exercise short

Do it in ten minutes, not an hour. Long sessions can become rumination.

TRY THIS
Set a ten-minute timer.
Photo for the tip: Do it on paper
TIP 25

Do it on paper

Writing gives distance and clarity. A phone note works, but paper feels calming for many.

TRY THIS
Use pen and paper for this exercise.
Photo for the tip: Redo it after the event
TIP 26

Redo it after the event

Compare what happened with your worst, likely and best cases. This gives you evidence for next time.

TRY THIS
Note which case was closest.
Photo for the tip: Share your result
TIP 27

Share your result

Telling a friend what actually happened, especially when it was better than feared, strengthens the lesson in your mind.

TRY THIS
Tell someone how it really went.
Photo for the tip: Use it for decisions
TIP 28

Use it for decisions

When unsure about a choice, list the worst, likely and best cases of each option. It clarifies without drama.

TRY THIS
Use it for one small decision.
Photo for the tip: Use it for health worries
TIP 29

Use it for health worries

If you worry about symptoms, do the exercise and then check with a doctor if needed. Do not use it to avoid medical advice.

TRY THIS
See a doctor if worries are about your health.
Photo for the tip: Use it for relationship worries
TIP 30

Use it for relationship worries

Before a hard conversation, write the cases. Often the likely result is a clearer, closer relationship.

TRY THIS
Write the cases for one difficult talk.
Photo for the tip: Use it for money worries
TIP 31

Use it for money worries

Worst, likely and best cases can show realistic options and next steps. It turns vague dread into a plan.

TRY THIS
List the cases and one action.
Photo for the tip: Use it for work worries
TIP 32

Use it for work worries

A looming deadline or review is easier with clear cases and actions. Share your plan with your manager if helpful.

TRY THIS
Write the cases for one work worry.
Photo for the tip: Hold the exercise lightly
TIP 33

Hold the exercise lightly

Do not turn the exercise into a ritual you must perform perfectly. It is a tool, not a test.

TRY THIS
Use it when helpful and set it aside when not.
Photo for the tip: Take care of your body first
TIP 34

Take care of your body first

Hunger and tiredness make worst cases look bigger. Eat, rest and then think.

TRY THIS
Eat something before you do the exercise.
Photo for the tip: Breathe between sections
TIP 35

Breathe between sections

Take a slow breath after writing each case. It keeps your body calm while your mind works.

TRY THIS
Breathe out slowly after each case.
Photo for the tip: Keep your worst-case sheet
TIP 36

Keep your worst-case sheet

Store the sheet. Reading it later shows how far reality was from your fears.

TRY THIS
File your paper in a folder called “Worry reality”.
Photo for the tip: Notice the relief
TIP 37

Notice the relief

When you see the real odds, many people feel an immediate lightness. Notice it and remember it for next time.

TRY THIS
Rate your worry before and after the exercise.
Photo for the tip: Be proud of facing it
TIP 38

Be proud of facing it

Looking directly at your fear takes courage. You are doing something brave.

TRY THIS
Tell yourself, “I looked at it and I am okay.”
Photo for the tip: Name the fear behind the fear
TIP 39

Name the fear behind the fear

Beneath “I might forget my lines” often sits “people will think I am not good enough”. Writing the deeper fear shows what you are really trying to protect, and it can be answered with kindness.

TRY THIS
Ask “and if that happened, what would it mean?” twice, and write the answer.
Photo for the tip: Do not wait for zero risk
TIP 40

Do not wait for zero risk

Almost nothing worth doing has zero risk. Accepting a small, survivable risk is what lets you live a fuller life. The aim is a realistic fear, not no fear.

TRY THIS
Say, “A small risk is the price of something worthwhile.”
