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.
I have found no greater satisfaction than achieving success through honest dealing and strict adherence to the view that, for you to gain, those you deal with should gain as well.
Believe nothing,
No matter where you read it,
Or who has said it,
Not even if I have said it,
Unless it agrees with your own reason
And your own common sense.
If man has good corn, or wood, or boards, or pigs to sell, or can make better chairs or knives, crucibles, or church organs, than anybody else, you will find a broad, hard-beaten road to his house, though it be in the woods.
Ambitious men spend their youth in rendering themselves worthy of patronage; it is their great mistake. While the foolish creatures are laying in stores of knowledge and energy, so that they shall not sink under the weight of responsible posts that recede from them, schemers come and go who are wealthy in words and destitute of ideas, astonish the ignorant, and creep into the confidence of those who have a little knowledge.
