There is as much greatness of mind in acknowledging a good turn, as in doing it.

The mind does not easily unlearn what it has been long in learning.

I was not born for one corner. The whole world is my native land.

Ponder for a long time whether you shall admit a given person to your friendship; but when you have decided to admit him, welcome him with all your heart and soul. Speak as boldly with him as with yourself.

The profit on a good action is to have done it.

The evil which assails us is not in the localities we inhabit but in ourselves. We lack strength to endure the least task, being incapable of suffering pain, powerless to enjoy pleasure, impatient with everything. How many invoke death when, after having tried every sort of change, they find themselves reverting to the same sensations, unable to discover any new experience.

What madness it is for a man to starve himself to enrich his heir, and so turn a friend into an enemy! For his joy at your death will be proportioned to what you leave him.
