What good is Experience?

Justin Kan from Justin.tv on the pro’s & con’s of having experience.

When I think about that first codebase today I want to vomit in my own mouth. I am glad that I no longer have access because I want to deny it ever existed. It was a mess of spaghetti code, and even though we built it quickly, it took a lot longer than it should have. Ironically, now that I have experience, I think experience is priceless. What’s made me change my mind?
