"Twenty years from now you will be more disappointed by the things you didn't do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover." Mark Twain
"Then something Tookish woke up inside him, and he wished to go and see the great mountains, and hear the pine-trees and the waterfalls and explore the caves, and wear a sword instead of a walking-stick." J.R.R. Tolkein
