A man should remove not only unnecessary acts, but also unnecessary thoughts, for then superfluous activity will not follow.

Is your cucumber bitter? Throw it away. Are there briars in your path? Turn aside. That is enough. Do not go on and say, "Why were things of this sort ever brought into this world?" neither intolerable nor everlasting - if thou bearest in mind that it has its limits, and if thou addest nothing to it in imagination. Pain is either an evil to the body (then let the body say what it thinks of it!)-or to the soul. But it is in the power of the soul to maintain its own serenity and tranquility. . . .

Look deeply. Don't miss the inherent quality and value of everything.

Just as nature takes every obstacle, every impediment, and works around it--turns it to its purposes, incorporates it into itself, so, too, a rational being can turn each setback into raw material and use it to achieve its goal.

Always follow these two rules: first, act only on what your reasoning mind proposes for the good of humanity, and second, change your opinion if someone shows you it's wrong. This change of mind must proceed only from the conviction that it's both correct and for the common good, but not because it will give you pleasure and make you popular.

The first rule is to keep an untroubled spirit. The second is to look things in the face and know them for what they are.
