I am not a regret type person. I don't believe in regrets. Lots of things you would do differently if you'd do it again, but you don't do it again, so you don't think about it. But that goes for life in general. You're only dealing with the knowledge you have at that time.
Everybody has certain things they wish they hadn't done in life. They wish they hadn't kicked their dog when they were ten or something. There are many things you can go back and have regrets about. I don't like doing that. But by the same token I do agree that when you get to a certain stage in life, you change. And you should change.
My father died very suddenly at sixty-three. Just dropped dead. For a long time afterward, I'd ask myself, Why didn't I ask him to play golf more? Why didn't I spend more time with him? But when you're off trying to get the brass ring, you forget and overlook those little things. It gives you a certain amount of regret later on, but there's nothing you can do about it. So you just forge on.
When I look back on my life, I don't have regrets about what I didn't do. If I'd become a musician, it could have ruined my life.
