Some suggestions for you :

Alexander the Great and his mule driver both died and the same thing happened to both.

Objective judgment, now, at this very moment. Unselfish action, now, at this very moment. Willing acceptance—now, at this very moment—of all external events. That's all you need.

Concentrate on what you have to do. Fix your eyes on it. Remind yourself that your task is to be a good human being; remind yourself what nature demands of people. Then do it, without hesitation, and speak the truth as you see it. But with kindness. With humility. Without hypocrisy.

The man of ambition thinks to find his good in the operations of others; the man of pleasure in his own sensations; but the man of understanding in his own actions.

Will any man despise me? Let him see to it. But I will see to it that I may not be found doing or saying anything that deserves to be despised.

Look beneath the surface; let not the several quality of a thing nor its worth escape thee.

Confine yourself to the present.

Alexander the Macedonian and his groom by death were brought to the same state; for either they were received among the same seminal principles of the universe, or they were alike dispersed among the atoms. Consider.

Were you to live three thousand years, or even thirty thousand, remember that the sole life which a man can lose is that which he is living at the moment; and furthermore, that he can have no other life except the one he loses.
