Constraints can force originality laziness would never discover.

With unlimited options, the easy answer is always available, and taking it is entirely rational. A constraint removes the easy answer, which is the only reliable way to force a search into territory nobody would visit voluntarily. Originality is often just what is left after the obvious was made impossible.

Add an artificial limit to something you are working on. Half the budget, half the length, one fewer element. See what the restriction makes you find.
