I'm a "what if" kind of person, mainly because I'm also a second guesser. I try not to live my life with regrets, because it has made me the person I am today....but I think everyone has at least a few they can name.
I regret not experiencing true college life. I stayed home & went to a community college, which is fine. But I've always regretted not leaving the comforts of home & being on my own, even for just a year. No roommate, no dorms, no parties, sororities, none of that.
I regret losing touch with friends, especially those from high school.
And lastly, I regret not buying the girls Christmas dresses last month when I saw them on sale because now I can't friggin find them anywhere!
