Most of the advice you're getting here is to monetize it, find what inspires, you, etc.

While well intentioned, that advice has been incorrect for me at least. What has worked has been to work on small, fast side projects. If you can only work on a project for two days, then pick projects you can finish in two days. Cut scope aggressively.

Frankly, my most successful projects are the ones that have been amonst the easiest.
