What have you done or not done that you regret?

Hi the most imporstant thing i regret is that I didn't study. I just wanted a job and I quit studies. I regret it deeply.I am sure if i would continued wit my university life would have had a different direction The only thing I dont regret is having children.they ahve made my life worth living

I regret that I did not keep my record book properly and I end up loosing it like three weeks before my practicum was over. Loosing the book meaning I loose marks and I have disappointed many people including myself. And worse this is the first case ever in my college...

I am still thinking right now to what have I not done that I regret. I have to honestly say I cannot think of anything that I regret not doing because I think i have lived most of my life to the fullest. Even if I got deprived with a few things in life my parents had a good reason to keep me away from those things. So I have to say nothing.
