One of my all-time favorite quotes (Thoreau). It gets more powerful the more you read it and better understand its message. I even memorized this quote so that I could be motivated by it more often.
“If one advances confidently in the direction of his dreams, and endeavors to live the life which he has imagined, he will meet with a success unexpected in common hours. He will put some things behind, will pass an invisible boundary; new, universal, and more liberal laws will begin to establish themselves around and within him; or the old laws be expanded, and interpreted in his favor in a more liberal sense, and he will live with the license of a higher order of beings.”
