Great post, good luck with the product! I recently did almost the exact opposite of this, quit work with a startup.

While I learned a lot of what you mention in your post (being a self-starter is a huge asset) at the time continuing work there seemed untenable. In retrospect, even though I was quitting into nothing and the next two months were some of the hardest times money-wise I've ever had to get through the decision was the best one I could have made.

I guess what I'm saying is congrats on taking control, which I think is more important then the vector of travel, I'm glad it's going well.
