Hardly an hour goes by that I don't 'shoulda woulda coulda' and it kept me in a funk for a long time, perpetuating the cycle. A lot of what happened couldn't be helped and it sucks, but, like you said; make it work for you. I didn't spend 45K on school but I spent a lot of money and 5 long, hard years trying to build a business only to realize the futility of it all and walking away when fate finally forced me out.
