Ronald Deibert:

Side projects spark our creativity by taking us away from The Grind.

The Grind is the problem that you beat yourself up over solving every single day. It’s the job you’re in, or the business you’re building. The Grind gets our best hours, our fullest attention, and the whole of our willpower.

A side project is just another type of creative outlet. (Via Chris Bowler.)
