Write “what to do” as “if… then…”

Change “I plan to do this” into “If I sit at my desk at 8 a.m. on Tuesday, I’ll start by writing the introduction.” Across 94 separate studies, people who used this phrasing were far more likely to achieve their goals — this effect is moderate to large. All it requires is rewriting one sentence; there’s no expense and almost no extra effort.

Cost

No cost at all. Each step takes just 1–2 minutes — simply write a sentence like “If… then…”. For example: “If I sit at my desk at 8 a.m. on Tuesday, I’ll start by writing the introduction.”

Benefit

When all 94 studies are combined, individuals who expressed their plans as “if… then…” statements had significantly higher success rates. This technique is known in psychology as implementation intentions. The effect size here is d = 0.65, which qualifies as moderate to large. Three key moments benefit from this approach: initiating action, resisting distractions, and disengaging from tasks that seem impossible to complete.

Book note

This method works only for goals you genuinely want to achieve. If a goal holds no personal value for you, writing multiple such statements won’t help. Additionally, most research participants were students, and the studies focused on health-related habits; results may not translate directly to workplace settings.
