Diligence promptly executes what intelligence slowly excogitates. Hurry is the failing of fools; they know not the crucial point and set to work without preparation. On the other hand, the wise more often fail from procrastination... Celerity is the mother of good fortune.
Baltasar Gracián, 1647 (tr. Joseph Jacobs, 1892)
Both diseases are diagnosed in one breath. Fools rush: no crucial point located, no preparation, motion mistaken for progress. But the wise have their own failure mode, and it is politer and just as fatal: the analysis extended past its useful life, the decision seasoned until the season is over. The winning sequence is asymmetric: slow on the thinking, then abruptly fast on the doing, with no gap between the two where doubt re-enters. Festina lente, hasten slowly, is not a compromise between speed and thought. It is both, in the right order, at full strength.
Practice
- Split every project into its two speeds explicitly: a thinking phase with an end date, an execution phase with a start time.
- Locate the crucial point before moving; one hour finding the hinge of the matter saves weeks of diligent work on its edges.
- Catch your own class of failure: if you ship regrets, add thought; if you ship late or never, add deadlines to deciding.
Use this when
- Use this on launches, filings, and repairs, anywhere a wrong-speed choice bills you either way.
- Use it in teams: pair the excogitators with the executors and make the handoff explicit.
Ignore this when
- Don't let the thinking phase reopen once execution starts; mid-sprint philosophy is just fear with a vocabulary.
- Don't apply double-speed rigour to trivia; small things are allowed to be merely done (maxim 35 prices attention).
A picture of it
Two software teams get the same brutal deadline. One starts coding within the hour, discovers the real requirement in week three, and ships a patched confusion. The other spends five silent days on the crucial point, which turns out to be one integration everyone had assumed away, then writes code at a pace the first team never matches, because nothing has to be done twice. Same deadline, both met on paper. Only one product survives contact with its users.
Think like a slow river, act like a burst dam. The order is the whole trick.
