Decide in advance
If–Then Planning: A Simple Way to Make Habits Easier to Start
Use a clear cue and a preplanned obstacle response to remove decisions from the moment you need to act.
By Thomas Kanze · Reviewed against the 30DayHero method
Key takeaway
Attach the action to a cue you will recognize, then write a second if–then response for the obstacle you are most likely to meet.
What you will leave with
Two testable sentences: one connecting a reliable cue to the normal action and one connecting your likeliest obstacle to a prepared response.
Who this is for
Use this when you genuinely intend to act but forget, start too late, negotiate at the cue, or repeatedly meet the same obstacle without a prepared response.
By the end, you will know how to
- What makes an if–then cue observable.
- How action plans differ from coping plans.
- How to test and revise the sentence in real life.
Turn intention into a situation
“I will read more” leaves the start floating. An if–then plan attaches the action to a recognizable moment: “If I finish dinner, then I will read at the table for 20 minutes.”
The cue can be a time, place, or event. Choose one that already occurs reliably and is close to where the action can happen.
Write a second plan for the obstacle
A cue starts the normal day. A coping plan handles the predictable difficult one: “If dinner runs late, then I will read one page before bed.”
Name the obstacle you actually meet: travel, fatigue, forgotten equipment, interruptions. Not an abstract lack of discipline.
Make both sides observable
The “if” should be easy to recognize and the “then” should describe a physical action.
- Weak: “When I feel motivated, I will exercise.”
- Clear: “When I close my laptop at 5:30, I will put on my walking shoes.”
- Coping: “If rain makes the route unsafe, I will use my indoor five-minute version.”
Test the plan in real life
Run the plan for several days and notice whether the cue arrives at the right time. If it repeatedly fails, move the cue or simplify the first step.
The sentence is not magic. Its value is that it makes the plan specific enough to test and improve.
Turn the idea into action
A step-by-step plan
- 1
Choose a goal you actually endorse
Specific planning helps translate an intention into action; it does not manufacture a reason you do not have. Write why the action matters before optimizing the cue.
- 2
Select a reliable “if”
Use a time, place, or event that occurs near the action: after breakfast, when the laptop closes, or at the first calendar reminder.
- 3
Write the physical “then”
Name the behavior and location precisely. “I will begin” is weaker than “I will open the document and write for ten minutes at the desk.”
- 4
Add one obstacle plan
Choose the obstacle most likely to occur, then connect it to a safe response that preserves the direction, often the hard-day minimum.
- 5
Test for three repetitions
Notice whether the cue arrives, whether it arrives at the right place, and whether the response is feasible. Change the sentence when the environment proves it wrong.
Before and after
Worked examples
A clear action plan
Before
“I will read tonight.”
After
“If I put my dinner plate in the sink, then I will read at the table for 20 minutes.”
Why it is stronger: The cue is an observable event and the action includes place and duration.
A coping plan for disruption
Before
“If I get busy, I will try harder.”
After
“If dinner ends after 9:00, then I will read one page before bed.”
Why it is stronger: The obstacle is recognizable and the response is already defined.
Common mistakes and the fix
Using a feeling as the cue
Fix: Replace “when motivated” with a time, place, or event you can notice.
Writing a vague response
Fix: Name the first physical action, duration or count, and location.
Planning for every possible obstacle
Fix: Start with the one most likely to break the plan; complexity can make the plan harder to remember.
Keeping a repeatedly missed cue
Fix: Treat the sentence as a test. Move the cue when real life shows it is unreliable.
Final checklist
Before you begin, make sure every statement below is true.
- Goal matters independently of the plan
- Cue is observable
- Cue occurs near the opportunity
- Response is physical and specific
- One likely obstacle named
- Plan will be tested and reviewed
Questions people ask
Are if–then plans scientifically supported?
A large research literature has studied implementation intentions. A 2006 meta-analysis synthesized 94 independent tests and reported a positive effect on goal attainment, while later work also emphasizes that effects depend on context and an underlying goal worth pursuing.
Can I write more than one if–then plan?
Yes, but begin with one normal cue and one important obstacle. A long decision tree is harder to remember and may recreate the very friction the plan is meant to remove.
What if the cue happens at a bad time?
That is useful evidence. Move the cue closer to a genuine opportunity, reduce the response, or change the environment rather than repeatedly blaming yourself.
Does the wording need to be exact?
Use wording you understand and can act on. The important properties are a recognizable situation and a specific response, not a ceremonial phrase.
