How ridiculous and unrealistic is the man who is astonished at anything that happens in life.

How much more grievous are the consequences of anger than the causes of it.

Waste no more time talking about great souls and how they should be. Become one yourself!

Never let the future disturb you. You will meet it, if you have to, with the same weapons of reason which today arm you against the present.

Nothing happens to any thing which that thing is not made by nature to bear.

Remember this-that there is a proper dignity and proportion to be observed in the performance of every act of life.

The happiness of your life depends upon the quality of your thoughts, therefore guard accordingly; and take care that you entertain no notions unsuitable to virtue, and reasonable nature.

It is the act of a madman to pursue impossibilities.
