Don't let your imagination to be crushed by life as a whole. Don't try to pictures everything bad that could possibly happen. Stick with the situation at hand. ...Then remind yourself that past and present have no power over you. Only the present.

To live happily is an inward power of the soul.

Say to yourself in the early morning: I shall meet today ungrateful, violent, treacherous, envious, uncharitable men. All of these things have come upon them through ignorance of real good and ill... I can neither be harmed by any of them, for no man will involve me in wrong, nor can I be angry with my kinsman or hate him; for we have come into the world to work together.

If any man despises me, that is his problem. My only concern is not doing or saying anything deserving of contempt.

I have often wondered how it is that every man loves himself more than all the rest of men, but yet sets less value on his own opinions of himself than on the opinions of others.

Do not disturb yourself by picturing your life as a whole; do not assemble in your mind the many and varied troubles which have come to you in the past and will come again in the future, but ask yourself with regard to every present difficulty: 'What is there in this that is unbearable and beyond endurance?'

Because your own strength is unequal to the task, do not assume that it is beyond the powers of man; but if anything is within the powers and province of man, believe that it is within your own compass also.
