On one regret

Obviously my four years in college weren't perfect, but they were absolutely the best years I've had so far (hopefully that will change in the near future). However, I'm unfortunately regretting something- not something I did, but something I didn't do. It's kinda too late to do anything about it now, and I'm just gonna have to deal with that. Even though I made many mistakes during my years in LA, this is probably the only thing I regret...and I didn't even do it.
