There are only so many decisions you can make in one day. And when you have made too many, you lose your willpower. Rolf Dobelli reports on the psychological studies that demonstrated this very clearly, and also shows some of the consequences for real-life situations such as the criminal justice system. But, apart from recommending a rest and a snack to recover, he doesn’t really offer much help in dealing with decision fatigue.
This matters to everyone, but I’m particularly interested in how it impacts on the creative process. We often talk about creativity as if it is some kind of magical thing bestowed on us from above, not least because the source of our best ideas is only partly and intermittently susceptible to conversant self-awareness. But the actual activity of generating creative products is essentially one of making decisions. Global decisions (what to produce, for whom, of what size, with commitments to which genre(s)); artistic decisions (expressive register, characterisation, emotional shape); technical decisions (key, voicing, texture, chord choice). Think how much time you spend in planning, day-dreaming, and trial-and-error tinkering - all those are species of decision-making activity.
