"There is one weakness in people for which there is no remedy. It is the universal weakness of lack of ambition! Persons, particularly salaried people who schedule their spare time, to provide for home study, seldom remain at the bottom very long. Their action opens the way for the upward climb, removes many obstacles from their path, and gains the friendly interest of those who have the power to put them in the way of opportunity."
-Napoleon Hill, as excerpted from Think and Grow Rich
