Constraints produce better creative work than freedom
Paradox of choice research (Barry Schwartz) shows that more options produce worse decisions and less satisfaction. In creative work, constraints — a limited colour palette, a specific format, a deadline, a thematic restriction — force creative problem-solving and often produce more original results than unlimited freedom. Twitter's 140-character limit created new forms of writing. 48-hour film festivals produce surprisingly good films. Set constraints deliberately when you have none.
Freedom is the enemy of creativity. Constraints are its engine.
