A man's worth is no greater than his ambitions.
Soon you will have forgotten the world, and soon the world will have forgotten you.
Confine yourself to the present.
If you are pained by any external thing, it is not this thing that disturbs you, but your own judgment about it. It is in your power to erase this judgment about it. If anything in your own nature gives you pain, you are who hinders you from correcting your opinion.
I search after truth, by which man never yet was harmed.
What we do in life ripples in eternity.
