What life lesson did you learn the hard way?
There are a few life lessons that I have learned over the years, one was that just because others tell me it is my fault doesn’t always mean that is the case (majority doesn’t always rule).
Another is that everyone has their own Ability and that means that just because X person can or does Y doesn’t mean that you have to do it also, or you can do it so you have to learn to be alright with your personal limitations, which is a lesson that I know but keep trying to not follow time and time again (guess I’m stubborn).
