I like to say "Do it scared." Sometimes I really want to do something but fear gets the best of me, like when I began mountaineering and had to face down a couple of knife-edged ridges or climb up a vertical rock face. It was an amazing experience and now I have no acrophobia at all. Stepping outside your comfort zone is a huge, humbling experience because you're opening yourself up to being vulnerable, where your faults and fears are laid bare. For me it's been acknowledging that I still have so much to learn about exercise and healthy eating. It's like when I dropped Greek after 3 weeks at Biola. Often there are moments when you just want to surrender and find excuses to stay the way you are. But remember: you don't magically improve yourself in a moment. On the other hand, you are capable of improving anything you want as long as you persevere.
