If you’re going to create, create a lot. Creativity is not like playing the slot machines, where failure to win means you go home broke. With creativity, if you don’t win, you’re usually no worse off than if you hadn’t played.
In fact, most people are being squeezed in their little cubicle, and their creativity is forced out elsewhere, because the company can't use it. The company is organized to get rid of variants.
I try to manage my day by my circadian rhythms because the creativity is such an elusive thing, and I could easily just stomp over it doing my administrative stuff.
