Same here! May I ask which field of programming you went into? And how you feel about being a programmer?
I often wonder how it might have been if I just had stayed with math. Especially, after years of doing regular programming for the Web, recently I had to develop a computational geometry library. It had been years since I graduated but really made me feel nostalgic. I think I lost something when I left the field, but then again life is a lot easier now...
