Absolutely. I still get cool ideas. It's a constant. But I don't often devote time to them, and fill most of my time in front of a computer on contract work. It's a frustrating thing for me, somewhat, when I hear and read of this obsession and expectation among developers (at least here on HN) to be working outside of work on side projects, as if that really shows you're something great as a developer.

My teenage sons are my primary project. Work is the side project.
