Hell is other people.
I have perceived that to be with those I like is enough.
All the people like us are We, And everyone else is They.
The longer we live, the more we find we are like other persons.
The way to learn whether a person is trustworthy is to trust him.
Don't worry that other people don't know you; worry that you don't know other people.
Whatever you may be sure of, be sure of this: that you are dreadfully like other people.
There is nobody so irritating as somebody with less intelligence and more sense than we have.
We find it hard to believe that other people's thoughts are as silly as our own, but they probably are.
We go on fancying that every man is thinking of us, but he is not; he is like us; he is thinking of himself.
The meeting of two personalities is like the contact of two chemical substances: if there is any reaction, both are transformed.
It is not the failure of others to appreciate your abilities that should trouble you, but rather your failure to appreciate theirs.
The source of all unhappiness is other people. As soon as you learn to think of other people as noisy furniture, the sooner you will be happy.
It is well to know something of the manners of various peoples, in order more sanely to judge our own, and that we do not think that everything against our modes is ridiculous, and against reason, as those who have seen nothing are accustomed to think.
Don't waste the rest of your time here worrying about other people—unless it affects the common good. It will keep you from doing anything useful. You'll be too preoccupied with what so-and-so is doing, and why, and what they're saying, and what they're thinking, and what they're up to, and all the other things that throw you off and keep you from focusing on your own mind.
