Never regret anything because at one time it was exactly what you wanted.
This life is what you make it. Not matter what, you're going to mess up sometimes, it's a universal truth.
As of today, I have absolutely no regrets. I think I am a mature person who can take things in stride. I'm grateful for people in my past. They helped me get to where I am, wherever that is. But now, I am thinking for myself and sitting in on all the business transactions.
