Its funny because its hard to gauge – the things you think are the most productive feed strongly into your confirmation bias, so maybe they aren't really that productive after all. But that's fine.

In general though, I prefer the idea of going "all in" in whatever I'm doing. If I'm going to play video games, I'm making sure I have a damn good time doing it. If I'm going to put in work, I'm gonna make sure it gets done. Distractions will do you in in both cases. Ruin your fun time and mess up your productivity.
