That's a pretty good lesson. It's better to do something and regret it than to not do something and regret it. While I'm here lying on my bed reading manga, I could be doing something else. I skipped out on lots of stuff. Who know where I might be if I just did something about it. Probably not here reading manga. Life is all about experience. Fill your life with meaningful stuff. You might regret doing it, but you'll learn something from it. That's how life works.
