what is the most important thing you’ve ever learned?

This is hard.  I’m only 17 years old, and I have a lot to learn still.  So far, I’ve learned some good lessons, and there are some that I should have already learned that I can’t get through my thick skull.  But, of the things I’ve learned, I really think the most important thing is that I know I can’t change other people.  I will never be able to be in someone else’s head controlling their thoughts or actions.  I will not be able to control their opinions or views.  I shouldn’t worry about what other people think because that person is not me.  If a person doesn’t agree with me, then we agree to disagree and that’s the end of it.  If they will not agree to disagree, then I will leave it at that and move on because there’s a chance that they aren’t worth fighting with if they aren’t mature enough to accept that we cannot change one another.  So, in all, the most important thing I’ve learned is that each person is an individual entitles to respectable opinions, and I shouldn’t worry about what anyone else thinks as long as it doesn’t directly affect me negatively.
