I could pin this a million times.. it is so perfect and so true. Self-centeredness is everywhere and it's such an awful quality to possess. Also, jealousy, people should be happy/proud of others accomplishments, not envious. people need to work to see all sides of a situation, not just their own. be kind, be the best person you can be.
In life we do things. Some we wish we had never done. Some we wish we could replay a million times in our heads. But they all make us who we are, and in the end they shape every detail about us. If we were to reverse any of them we wouldn't be the person we are. So just live, make mistakes. Have wonderful memories. But never ever second guess who you are, where you have been, and most importantly where it is you're going.
