Great post! I came from consulting into start-up world also (although I'm non-technical) and while you definitely have to re-learn many things to adjust to building a company, there are many many valuable lessons from working in that environment that entrepreneurs are all too quick to dismiss.

But the bottom line of your post is definitely the right summary: Do what feels right when it feels right, and you'll be fine. You can't lose when you're choosing between multiple interesting options. And as soon as your current path becomes uninteresting, look elsewhere.

Thanks for posting.
