What is life without a few hiccups? Honestly, is that sort of life even worth living? We should make mistakes. Try new things. Make mistakes. Fall and walk again. Then fall some more. take some rest if we don't have the energy to get up. Then get back on our feet and walk again.
Making mistakes is human nature. Ask your parents? They made you. But, jokes aside, we don't really learn the importance of things unless we make mistakes. We can learn that some things are bad from books, history or our parents. But, we don't really understand the nuances unless we really delve into them.
I am not saying willingly jump off the bridge or something. That's not the kind of mistake I am talking about. If you think that way, mistakes aren't your biggest problem. You are. But, leaving the oddball aside, I think we should experience different kinds of things from all walks of life.
