As far as I know, the main thing is to do a lot of it, and with purpose.

Depending on your personality, this may be a big ask — if you get discouraged or distracted easily, for instance.

On the other hand, it's a very accessible skill: pen and paper are easy to come by.

Personally, I've always felt rewarded by doing it. It soothes something in me, so I haven't had the struggle with self-motivation that some report.

I think that's a key to getting good at many things, really: find some emotional satisfaction from what you're doing, and the motivation will follow. As opposed to simply saying "I want to be good at X" and mechanically pushing yourself to do it. If you don't have some baseline love for the activity, you may learn to dread it, by that approach.
