Know that you're gonna screw up, and be OK with it, and do better next time.

It is folly for an eminent man to think of escaping censure, and a weakness to be affected with it. All the illustrious persons of antiquity, and indeed of every age in the world, have passed through this fiery persecution.

Old age is a special problem for me because I've never been able to shed the mental image I have of myself - a lad of about 19.

Why do people talk of the horrors of old age? It's great. I feel like a fine old car with the parts gradually wearing out, but I'm not complaining,... Those who find growing old terrible are people who haven't done what they wanted with their lives.

A major advantage of age is learning to accept people without passing judgment.
