A life lesson for me is how do you muster the courage to take on a new risk? Whether it's starting up a business or taking on a new project or expedition. I think the risks that we take are all relative to the risk-taker.
Just recently I was in Target with my mom shopping and out of the blue I see this father and his two daughters and he says 'Can they get a picture with you?' And I'm thinking to myself 'Am I the one millionth customer or something?'
