You need to be prepared for firm decisions and action, without losing gentleness towards those who obstruct or abuse you. It's as great a weakness to be angry with them as it is to abandon your plan of action and give up through fear.

Everything that exists is in a manner the seed of that which will be.

Since it is possible that thou mayest depart from life this very moment, regulate every act and thought accordingly. But to go away from among men, if there are gods, is not a thing to be afraid of, for the gods will not involve thee in evil; but if indeed they do not exist, or if they have no concern about human affairs, what is it to me to live in a universe devoid of gods or devoid of Providence? But Gods there are, undoubtedly, and they regard human affairs; and have put it wholly in our power, that we should not fall into what is truly evil.

If you are pained by any external thing, it is not this that disturbs you, but your own judgment about it.

Remember that even if you were to live for three thousand years, or thirty thousand, you could not lose any other life than the one you have, and there will be no other life after it. So the longest and the shortest lives are the same. The present moment is shared by all living creatures, but the time that is past is gone forever. No one can lose the past or the future, for if they don't belong to you, how can they be taken from you?

Live each day as if it be your last.

He who does wrong does wrong against himself. He who acts unjustly acts unjustly to himself, because he makes himself bad.
