I leave you with a few thoughts from John McCain's Acceptance Speech. No matter your politics or beliefs, these words ring true.
"If you find faults with our country, make it a better one. If you're disappointed with the mistakes of government, join its ranks and work to correct them. Enlist in our armed forces. Become a teacher. Enter the ministry. Run for public office. Feed a hungry child. Teach an illiterate adult to read. Comfort the afflicted. Defend the rights of the oppressed. Our country will be the better, and you will be the happier. Because nothing brings greater happiness in life than to serve a cause greater than yourself. "
So volunteer. Make a difference. There are people who need the gifts you have to offer. So find a cause and "be the change you want to see in the world."
