I think people should take responsibility more often.

For example take me: who treats her parents badly because her parents treat her badly. I never wanted to be like my parents yet here I am, acting like them. I will take responsibility for my actions by apologizing to them and admiting that I was wrong treating them like that. People need to understand why do we have good and bad and something in between constantly in life. For life is chaotic, and life is chaotic because we as individuals aren't perfect as in perfectly good or perfectly bad. And that's why there's happiness, because if we were perfect, nothing that makes us happy will exist and so that thing would be out of our comperhension. Because we have flaws, we need to strive to be a good person in order to find happiness. And that means: learning from your mistakes by taking accountability for your actions. By that, we improve our relationships (of any kind, whether it be romantic, friendship, family etc...) and relationships are the most important thing in our lives, because we humans are social creatures. Earth is classroom, history is a teacher, and our actions are a book. We cannot blame others nor ourselves, because we'll never get to learn what responsibility is.
