An acorn that only thinks as an acorn will never become a mighty oak. You are undoubtedly capable of more than you ever dreamed is possible for you. Become the person who would achieve your goals. Spend an extra hour each day in the study of your chosen field. Give more than you must.
Nothing advances until somebody does more than they are paid to do.
Always deliver more value than others expect. Don't require others to acknowledge your generosity. Make time for what you love. If you don't live fully, you deny the world your potential contributions. What you love reveals the value you bring to the world.
