How to make the most of my acceptance into UofC MBA as an aspiring entrepreneur?

I have attempted to launch two companies. Both of which did not gain traction, but I believe that what I have learned from my attempts was well worth the cost and time.<p>University of Chicago is ranked second among the top 25 College and Business Schools by Entrepreneur magazine. I am very excited to collaborate with UofC's alumni, students and professors to learn how to start a promising new venture.<p>Any advise from the HN community concerning techniques, strategies, advice or anecdotes to ensure I make the most of my studies at U of C as an aspiring entrepreneur would be great!<p>Thanks, Steve
