After my last (also my first) company failed - my credit was heavily damaged (and after nearly 4 years it has yet to fully recover), repaying debt can take quite a long time (I spent the last 3.5 years working at a well paying corp job and I was only able to fully settle the debt early last year), and due to bad advice from a (very) expensive accountant the IRS was a thorn in my side for 2.5 years.
But, I'm about to do it again as the experience is amazing and a _fantastic_ education.
