Man is a creature that can get accustomed to anything, and I think that is the best definition of him.

Above all, avoid lies, all lies, especially the lie to yourself. Keep watch on your own lie and examine it every hour, every minute. And avoid contempt, both of others and of yourself: what seems bad to you in yourself is purified by the very fact that you have noticed it in yourself. And avoid fear, though fear is simply the consequence of every lie. Never be frightened at your own faintheartedness in attaining love, and meanwhile do not even be very frightened by your own bad acts.

Man, so long as he remains free, has no more constant and agonizing anxiety than find as quickly as possible someone to worship.

That's always the way with fanatics; they cross themselves at the tavern and throw stones at the temple.

Only by self-respect will you compel others to respect you.

My friends, ask gladness from God. Be glad as children, as birds in the sky. And let man's sin not disturb you in your efforts, do not feat that it will dampen your endeavor and keep it from being fulfilled, do not say, Sin is strong, impiety is strong, the bad environment is strong, and we are lonely and powerless, the bad environment will dampen us and keep our good endeavor from being fulfilled. Flee from such despondency, my children! There is only one salvation for you: take yourself up, and make yourself responsible for the sins of men.
