what is your biggest regret or hardest life lesson?

I think not saying the things I should have said...the old saying that we only regret the things we don't do is so true, we all think we have our loved ones forever, I say we should tell the people we love that we do love them while we have them and don't hold back...its too late for me, I guess I learnt the hard way..

My biggest regret is when I was fresh out of high school and started college I didn't take college seriously. I would much rather be out hanging with my friends then going to my classes. So my first year of college I failed out and lost my financial aid. I now work at a convinience store making a little over minimum wage and I often wonder what I would have become if I hadn't screwed up my college life.I would do it WAY differently if I had it to do over again.
