I think writing is my favorite thing to do. Every day I don't write I feel a little like I fucked up. I'll forget that insane sense of fulfillment and boost of energy that I get from doing it, stop for a week, then be blown away again when I write even only as much as 150 words. I'm getting more disciplined, though. I spend a lot of my free time either reading or researching. I never wanted to go to college, especially for an English degree, so instead I'm watching these videos of Brandon Sanderson's fantasy and sci-fi writing class at BYU. I've got a little notebook and I just fill it in as I watch. I'm not very good, but I can also see myself improving the more I practice. I also like to do copywork. I write down passages from stories that I felt were moving or just really cool.
Most of my coworkers at my new job are either artists or fighters. They are extremely dedicated and disciplined. Just talking to them about what they do fills me with energy and makes me want to go hard as fuck all the time.
