This is the conclusion that I've come to as well after trying for way too long to find inspiration to those things that I either want to do (on some level) or need to do.

Habits are things you do that don't have a big hurdle. For years I've been able to run without feeling that there's a great resistance in doing it (I don't normally identify as a runner). But picking up some work that I want to do but don't feel it's the right moment to do has been a lot harder. Lately I've had some progress with at just doing tasks because it's become a habit when I have some time over.
