I used to do a TON of work on the side. For years and years, when I finished work, I went home and worked on something else- writing something for myself, or a project for someone else. As a creative person I never stop creating. I freelance less nowadays. Between running and creating games for my oldest son (in college) and making up worlds with my youngest son, I get my itch scratched collaboratively nowadays. I still make things, but more of them are for myself and my family now.
That said, if you have short projects that I sound like a good fit for, reach out. I still love new challenges, and I am always up for a new experience.
