Lord Chesterfield (September 22, 1694 - March 24, 1773)
Lord Chesterfield in Wikipedia
Be wiser than other people if you can; but do not tell them so.
If you are not in fashion, you are nobody.
Persist and persevere, and you will find most things that are attainable, possible.
The more one works, the more willing one is to work.
Wrongs are often forgiven, but contempt never is. Our pride remembers it forever.
Everything else you grow out of, but you never recover from childhood
A book holds a house of gold
Take the attitude of a student, never be too big to ask questions, never know too much to learn something new.
