I think that's the single best piece of advice: constantly think about how you could be doing things better and questioning yourself.

A low-minded person should not be given good advice.

Why should we take advice on sex from the pope? If he knows anything about it, he shouldn't!

Be yourself, chase your dreams, and just never say never. That's the best advice I could ever give someone.

In offering to you, my countrymen, these counsels of an old and affectionate friend, I dare not hope they will make the strong and lasting impression I could wish; that they will control the usual current of the passions, or prevent our nation from running the course, which has hitherto marked the destiny of nations.

Let your countenance be pleasant, but in serious matters let it be somewhat grave.
