I'm a Python developer because it's what I do. It's wrapped up in my self-identity. If I suddenly couldn't code Python, Django or JS anymore, I'd almost certainly have an identity crisis.
When I imagine doing something else for a living, any other career, my reaction to myself is always: Are you serious? That would be Hell.
I had specific reasons for learning to code in the beginning, but those reasons don't apply anymore. I guess is like physics. You need an initial push to get a body in motion, but after that the motion sustains itself. The original push is irrelevant. I code.
