I like to build side projects. As a general rule, I always have a few "in the works". And when I do, I always find myself making the same mistake-ish: trying a bunch of new things, as in languages, libraries, paradigms, concepts, whatever. The bad part is that it usually derails the whole project as I hit roadblocks, unsupported features, abandoned dependencies, etc. The good bit is that I get to keep learning things even if my day job is with a very stable and boring tech stack. And I'm usually familiar with the cool shiny toys before they become mainstream. So that's when we're talking about tech stuff. For the rest, I procrastinate a lot here on HN and on Wikipedia and similar places, so I just read a lot on whatever seems interesting.
