Why 'If-Then' Plans Outperform Good Intentions
A large meta-analysis found that simply deciding in advance when, where and how you'll act makes you substantially more likely to follow through.

The short version
Pairing a goal with a specific 'if this happens, then I'll do that' plan is associated with meaningfully better follow-through than intention alone.
Why it matters
The specific mental act of pre-deciding a cue and a response appears to do real work beyond simply wanting something more, likely by making the intended action easier to trigger automatically when the moment arrives.

What it may mean
In real life
Someone who says 'I'll write when I get a chance' rarely does; someone who decides 'when I finish breakfast, I will open the document' is drawing on the same mechanism this research points to.
Try this
For one goal you keep intending but not doing, write a single if-then sentence specifying the exact situation and exact action, and use that instead of a general intention for a week.
Evidence confidence
Strong confidence
A large, heavily cited meta-analysis with a consistent effect across many independent studies, though the underlying literature leans on self-report measures and may include some publication bias.
