I have a PhD in Physics. 8 university years to eventually discover that I am not that interested in research for a living (and not that good at it), even though my speciality was great (Astrophysics). Ten years later, I'm a senior programmer with very interesting things to build, and passion doesn't fade. I don't regret having done all that Physics (it was freaking Astrophysics, dude!), but I know I would have been miserable after a while, not doing what I was really good at.
