Not less than two hours a day should be devoted to exercise, and the weather should be little regarded.

I am an Epicurean. I consider the genuine (not the imputed) doctrines of Epicurus as containing everything rational in moral philosophy which Greek and Roman leave to us.

I never considered a difference of opinion in politics, in religion, in philosophy, as cause for withdrawing from a friend.

Leave all the afternoon for exercise and recreation, which are as necessary as reading. I will rather say more necessary because health is worth more than learning.

Friendship may, and often does, grow into love, but love never subsides into friendship.

The older I get, the more I appreciate the idea of being thrown together with a group of people you might have a lot in common with, or nothing at all. You don't have the option of doing anything other than making your family relationships work - forever. I like that.

When I was growing up, my mother was always a friend to my siblings and me (in addition to being all the other things a mom is), and I was always grateful for that because I knew she was someone I could talk to and joke with, and argue with and that nothing would ever harm that friendship.

I think I understand the relationships between different people within the company: people who are straightforward employees, people who can impact the bottom line, and people who share in the bottom line. I don't think you can understand inequality in America unless you understand what's driving profitability.
