We can only be the best that we can be. Try harder to take responsibility for your actions and to take control of your situation. Do your best to help those around you to become the best they can. We cannot always be selfish, but we must remember that we all are a piece of the puzzle. We must work together to achieve a finished product.
Look around you today - how can you help someone near you achieve their dream? Are you a help or are you a hinderance in their way? Work out the kinks and strive to help others, and this in turn will help you.
"Let us therefore follow after the things which make for peace, and things wherewith one may edify another." Romans 14:19 (King James Version)
