When you have trouble getting out of bed in the morning, remember that your defining characteristic-what defines a human being-is to work with others.

The whole universe is change and life itself is but what you deem it

Retire into thyself. The rational principle which rules has this nature, that it is content with itself when it does what is just, and so secures tranquility.

Keep yourself simple, good, pure, serious, and unassuming; the friend of justice and godliness; kindly, affectionate, and resolute in your devotion to duty.

No one wearies of benefits received.

If you are distressed by something, it is due to your own estimate of it; and you have the power to change it at will.

Without a purpose, nothing should be done.
