"I believed I was invincible. If MIT couldn’t burn me out, nothing else ever could. It took roughly three months before BCG disproved my “burn-out proof” theory" I also wonder if this is a 'getting older' thing. When I was young, I had all the time to do anything. I had no money or opportunity, so when an opportunity came along I would go 100% into it. Now that I have money, education, and experience, I have nearly endless options. I try to do the ones that suck least and have good ROI.
