To live happily is an inward power of the soul.
The happiness of your life depends upon the quality of your thoughts: therefore, guard accordingly, and take care that you entertain no notions unsuitable to virtue and reasonable nature.

Whatever is in any way beautiful hath its source of beauty in itself, and is complete in itself; praise forms no part of it. So it is none the worse nor the better for being praised.
Never esteem anything as of advantage to thee that shall make thee break thy word or lose thy self-respect.
Men exist for the sake of one another. Teach them then or bear with them.
Loss is nothing else but change, and change is Nature's delight.
