When we act pugnaciously, and injuriously, and angrily, and rudely, to what level have we degenerated? To the level of the wild beasts. Well, the fact is that some of us are wild beasts of a larger size, while others are little animals, malignant and petty.

Don’t consent to be hurt and you won’t be hurt – this is a choice over which you have control

Men are disturbed not by the things that happen, but by their opinion of the things that happen.

It is not my place in society that makes me well off, but my judgements, and these I can carry with me... These alone are my own and cannot be taken away.

When therefore we are hindered, or disturbed, or grieved, let us never attribute it to others, but to ourselves; that is, to our own principles. An uninstructed person will lay the fault of his own bad condition upon others. Someone just starting instruction will lay the fault on himself. Some who is perfectly instructed will place blame neither on others nor on himself.

We can't control the impressions others form about us, and the effort to do so only debases our character.

Whenever you are angry, be assured that it is not only a present evil, but that you have increased a habit.
