I picked up a lot of student loan debt in college... I think it was over $50k, maybe actually around $70k? It's hard to remember b/c it was an overwhelming number, so I just put it out of my mind and worked as hard as I could.
I eventually paid it off working as a consultant, and then I was able to quit working and start my first company. Thank goodness, b/c I hated corporate life.
That's the most I've ever been in debt. How about you?
