Fast forward to now. I'm over 40. I have loads of things I wanted to accomplish by now. Every day I start out at 4:30am good but once the wife and kids are up. There goes my productivity.
Plus, coding is all I have ever done. I started with c++ at 13 and to sit and write code for my own goals just brings me so much happiness. To see it working, see others using it. Hell, even banging my head against the wall solving problems makes me happy.
