WOOP stands for Wish, Outcome, Obstacle, Plan. You picture a goal and its best result, then deliberately picture the inner obstacle most likely to stop you, and finish with an “If [obstacle], then I will [action]” plan. This pairing of positive thinking with honest obstacle-spotting, called mental contrasting with implementation intentions, turns vague health goals into specific next moves.
Why positive visualization alone falls short
Imagining success feels good, and that is part of the problem. Picturing yourself fitter or calmer can give you a small sense of having already arrived, which takes the urgency out of acting. Mental contrasting fixes this by placing the obstacle right next to the dream, so your mind registers that there is a gap to close and a plan is needed.
The approach has a reasonable evidence base. A 2021 meta-analysis of 21 studies with nearly 16,000 participants found that mental contrasting with implementation intentions improved goal attainment with a small to medium effect, and that the effect was stronger when delivered with a person guiding it. For eating specifically, a 2025 randomized trial in adults with excess weight found that adding one week of online WOOP-style training to a standard weight-management program reduced snacking and led to greater BMI reductions than the program alone.
The four steps of WOOP
1. Wish
Name one wish that is challenging but doable within a set time, such as the next four weeks. Keep it to a few words.
- “Stop grazing after dinner.”
- “Walk four times a week.”
- “Bring lunch to work most days.”
2. Outcome
Ask: what is the best thing about fulfilling this wish? Choose one outcome and spend a minute or two imagining it in detail. How would you feel waking up? What would your evenings look like? Let yourself enjoy it.
3. Obstacle
Now ask: what is the main thing in me that stops me? Focus on inner obstacles, such as a feeling, a habit or a thought, rather than outside circumstances you cannot control. Then picture that obstacle as vividly as you pictured the outcome.
- “When I sit on the couch after dinner, I feel bored and restless.”
- “I tell myself I’m too tired to walk after work.”
- “In the morning rush, packing lunch feels like one more chore.”
4. Plan
Write one if-then plan that links the obstacle to a specific response:
If [obstacle], then I will [action].
- “If I feel restless on the couch after dinner, then I will make a cup of herbal tea and start a puzzle.”
- “If I think ‘too tired’ after work, then I will put on my shoes and walk for just ten minutes.”
- “If packing lunch feels like a chore, then I will pack it the night before while dinner cooks.”
Worked examples for health goals
| Wish | Outcome | Inner obstacle | If-then plan |
|---|---|---|---|
| Eat breakfast every weekday | Steady energy, less mid-morning snacking | “I’m not hungry yet and I’m rushed.” | If I’m not hungry at 7, then I’ll pack a yogurt and fruit to eat at 9. |
| Go to bed by 10:30 | Waking up rested | “One more episode.” | If the episode ends after 10, then I’ll turn off the TV and start my bedtime routine. |
| Drink more water | Fewer headaches, fewer “fake hunger” moments | “I forget until I’m thirsty.” | If I sit down at my desk, then I’ll fill my water bottle first. |
| Strength train twice a week | Feeling strong carrying groceries | “I feel self-conscious starting.” | If I feel nervous, then I’ll do the 15-minute routine at home first. |
| Fewer takeout meals | Saving money, feeling lighter | “I’m exhausted and nothing is ready.” | If I get home with no plan, then I’ll make the eggs-and-toast backup meal. |
A five-minute WOOP worksheet
Copy this onto a card or into your journal and fill it in without overthinking:
- My wish for the next four weeks (a few words): ______
- The best outcome, and how it would feel: ______ (close your eyes and picture it for one minute)
- The main thing in me that holds me back: ______ (picture the moment it usually shows up)
- Where and when that obstacle appears: ______
- If [obstacle], then I will: ______
Step 4 is optional but useful. Knowing that the obstacle tends to appear “on the drive home” or “at 9 p.m. in the kitchen” tells you exactly where to put a reminder.
Common mistakes and fixes
- Too many obstacles. Pick the single biggest one. You can run a second WOOP later.
- Vague plans. “Then I’ll be healthier” is not a plan. Name a specific action, time or place.
- Outside obstacles only. “My schedule is busy” is real, but ask what you feel or do in response, and plan for that.
- Skipping the imagery. The vivid picturing of both outcome and obstacle is what makes the method different. Give each step a full minute.
- Wishes that are too easy or too big. If you are already sure you will do it, or certain you cannot, adjust the wish.
Making WOOP a daily habit
- Morning WOOP (5 minutes): one wish for today, one obstacle, one if-then.
- Write it down on a sticky note, in your planner or as a phone reminder timed for when the obstacle usually appears.
- Evening check (1 minute): did the obstacle show up? Did you use the plan? What would make the plan work better tomorrow?
- Weekly review: keep plans that worked, rewrite ones that did not, and move on to a new wish when the old one is mostly automatic.
WOOP also helps with emotions. If your obstacle is a feeling, such as discouragement after a slip, your plan can be emotional too: “If I feel like giving up after overeating, then I’ll remind myself one meal does not erase a week, and plan my next meal.”

When WOOP may not fit
WOOP works best for goals that are within your control. If your wish depends heavily on others, or if you are facing serious health problems, low mood or disordered eating, work with your doctor or a qualified professional on a plan that suits you.
Key takeaways
- Pair a vivid picture of your goal with an honest picture of your biggest inner obstacle.
- Write one “If [obstacle], then I will [action]” plan per wish.
- Keep wishes challenging but realistic, and obstacles internal and specific.
- Do a five-minute WOOP in the morning and a one-minute check in the evening.
- Rewrite plans that do not work; the method improves with practice.
FAQ
Isn’t thinking about obstacles negative?
It is realistic, not negative. Seeing the obstacle before it arrives is what lets you plan around it.
How many WOOPs should I run at once?
Start with one. Once that plan runs smoothly, add another.
