Laugh, laugh, laugh. If we laugh enough we can consider our lives a success. Too much self-introspection can put your mind in a stew. The world does not revolve around you. By looking outside yourself you can find much to entertain and satisfy.
Curiosity can be the key.
That was mine. When I understood that my curiosity was most important my fragile ego got tough and took a backseat. My interaction with people changed as well. They began to take me much more seriously. Social Evolution can help make some sense of it all.
