Sounds like we are a lot alike; cycling is really the only thing I've done consistently (18 years now) and even then there are gaps.
I've learned that when I get a few days away from my routine, I realize how enveloped I am in it and how much better my life is without it.
Right now I'm learning languages, and the sunk cost is real so I really don't want to quit.
I'm also coding, but to be honest, once I figured out the complicated stuff it's basically a second job now. I want to launch my site because I believe in the product, but its probably going to be more pain than its worth.
