Self-imposed deadlines

Bind yourself to interim deadlines instead of one distant due date.

Why it works

Present bias makes us discount future costs steeply, so a single far-off deadline invites last-minute cramming and quality collapse. Imposing earlier, spaced, externally-known deadlines pulls the cost forward into a region where present-biased preferences still respond — converting one impossible sprint into several feasible ones.

How to do it

1. Break the goal into milestones each with its own date, not just a final deadline.
2. Make the interim deadlines public or owed to someone, so they carry real weight.
3. Space them evenly rather than back-loading; the point is to deny yourself the cliff.

Evidence

A classic experiment found that students who imposed their own evenly-spaced deadlines performed better than those given a single end-of-term deadline — direct evidence that self-imposed deadlines work, though not as well as externally enforced ones. (rct)

Self-set deadlines beat no deadlines but underperform externally enforced ones; people set themselves too much slack.

Common mistake

Setting only a final deadline (or interim ones with no consequence), which present bias treats as no deadline at all until the last moment.
