A reasonable man adjusts himself to the world. An unreasonable man expects the world to adjust itself to him. Therefore all progress is made by unreasonable people.
It is when those who are not strong enough have made some moderate amount of progress that they fail and give up.
As in the case of making a mound, if, before the very last basketful, I stop, then I shall have stopped. As in the case of leveling the ground, if, though tipping only one basketful, I am going forward, then I shall be making progress.
