Assuming you're telling a true story of you doing well, don't get too cocky — because not because you did well in the past, doesn't automatically you're going to do well in the long-term.
Life is a process and things get stronger as it goes, sometimes it gets nice or not, yet we are expected to be pliable instead of static. Op made the right step by doing what he thinks, as whatever a man thinketh so he is, but it doesn't guarantee that a person who did succeed from their previous thought won't face some disputes again. That's why it's always good to be free and forget the past, empty yourself, OP, and be useful to your friends and family, like a cup; its usefulness is determined by its emptiness. Let go of how they treated you and help them if you wish. Good luck.
