This always amazed me too. There will always be greener grass somewhere. I was surprised to find that my mid-west mindset could be so stark in comparison to some of the valleys. For me, two years ago my dream was to do exactly what I'm doing now: writing code at a reputable tech company and learning more every day. That, and I make enough money to do everything else I want if I don't blow it on an overpriced car or <insert status symbol>.
Building a company and walking away with 6 million is life changing. Too many people seem to think selling your company means you should never need to work again. What it means, is that you're freer to continue to pursue the projects you want. Seems like a huge inflection point to me.
