When you close your doors, and make darkness within, remember never to say that you are alone, for you are not alone; nay, God is within, and your genius is within. And what need have they of light to see what you are doing?

Men are not troubled by things themselves, but by their thoughts about them

To know that you do not know and to be willing to admit that you do not know without sheepishly apologizing is real strength and sets the stage for learning and progress in any endeavor.

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.

Do you know that disease and death must needs overtake us, no matter what we are doing?... what do you wish to be doing when it overtakes you?... If you have anything better to be doing when you are so overtaken, get to work on that.

The two powers which in my opinion constitute a wise man are those of bearing and forbearing.

Seek not that the things which happen should happen as you wish; but wish the things which happen to be as they are, and you will have a tranquil flow of life.
