Dijkstra's 3 rules for project selection

It's along the lines of how to come up with good ideas, but I'm not sure that it's actionable. Almost every problem I think about could be reasonably solved by the next guy. There's the other caveat that if you don't have other people working on similar things you're probably working on a pain point nobody has. I like PG's more actionable approach about picking problems you yourself experience, regardless of who else might be working on it.
