The story: Back in May, I was terminated. In early 2012, I asked my manager for an MBA recommendation and he gave me a conditional one. "I cannot give you one now. You complete this project for me and I'll give you a positive recommendation." The project was finished this January, past R2 deadlines for all schools. He wanted to write me a recommendation for R3 but I told him that would be crazy. So I pushed back my target applications to this year. This April, my team moved to a new department with a new head who made the decision to let me go. My boss' fund didn't generate enough fees to have two analysts, and since I was planning to leave anyway, I was the odd man out - so he says

On the somewhat positive side, they paid me a small severance and are letting me say that I resigned. I was hesitant about finding a job because I didn't want to burn bridges by joining a firm and leaving for an MBA in 9 months. So I started a company with a friend, but I am not taking a salary, and we have not seen revenues yet. I could care less about money at this point - I have enough saved to last five years.

So what do you think? I'm applying this year, but doubtful if I get into any of my schools. I'm targeting MIT, Wharton, Booth, Columbia, NYU. Now I'm also adding Yale, Tuck, UVA, Cornell to that list and I'm even doubtful about those schools. What if I said I want to go into entrepreneurship, and that I quit and started my own company to learn how it would be before I actually went to school?
