I've come to embrace the notion that I haven't done enough in my life. I've come to confirm that one's title, even a title like president of the United States, says very little about how well one's life has been led. No matter how much you've done or how successful you've been, there's always more to do, always more to learn, and always more to achieve.
But man is a fickle and disreputable creature and perhaps, like a chess-player, is interested in the process of attaining his goal rather than the goal itself.
There are two kinds of success. One is the rare kind that comes to the person who has the power to do what no one else has the power to do. That is genius. But the average person who wins what we call success is not a genius. That person is a man or woman who has merely the ordinary qualities that they share with their fellows, but has developed those ordinary qualities to a more than ordinary degree.
Don't aim for success if you want it; just do what you love and believe in, and it will come naturally. Despite everything, I believe that people are really good at heart.
When nature removes a great man, people explore the horizon for a successor; but none comes, and none will. His class is extinguished with him. In some other and quite different field, the next man will appear.
