I had a similar feeling of pointlessness. For me I realized that that feeling stemmed from viewing myself as powerless and small in the face of the complexity and chaos of the world. How could I possibly make any meaningful change from where I am? I came to believe that everyone is in that same boat. Those we look up to as having made "meaningful" change were just the right people in the right place and time and had relatively little control over that destiny. That probably won't be me or you, but it definitely won't happen to someone that starves to death, dies from a preventable illness or is just fighting to survive each day. So, I came to believe that the greatest leverage I have for making change in the world is to remove barriers for as many other people as possible and just increase the pool of people that might be the right person in the right place and time to solve the really big problems we all face. Furthermore, spreading the idea that helping others is the best way to help the world can leverage a network effect. You might help the person that helps the person that is then able to solve a really big problem.
