It’s difficult to play a sport or a board game with rules; guides for things you can and can’t do, time limits, a definition of what’s in and out of bounds. It’s these limits that make the game or sport fun to play. The same goes with creative work.
I do my best work when I’m bound by rules: a deadline, a limited set of materials, a limited colour palette, a limited surface on which to create. All of these limits are useful boundaries that help guide and inform the choices about what I make and why.
