I love reading singer/songwriter Christine Kane's blog. She's a very talented writer and has a lot of wonderful advice to share. In her entry on building courage, she says:
"Courage is like a muscle. Just as you wouldn’t go into the gym for your first time and lift a 100-pound dumbbell - you don’t have to begin building courage by running for President. (Though, lots of people would probably vote for you at this point.)"
