"Whatever your age, your upbringing, or your education, what you are made of is mostly unused potential. It is your evolutionary destiny to use what is unused, to learn and keep on learning for as long as you live. To choose this destiny, to walk the path of mastery, isn't always easy, but it is the ultimate human adventure. Destinations will appear in the distance, will be achieved and left behind, and still the path will continue. It will never end."
George Leonard
