Cycles are hard to break, but you are one step closer by just coming here! Everyone wants to make an impact on humanity and we all do. Sometimes we just don't realize how many people we reach each day. How we treat other people effects how they will treat people as well. So if you do a good deed or just are plain polite, you are having an effect on people because they will pass it on! Your life does have a purpose. Don't give up and keep pushing forward.
