Nature which governs the whole will soon change all things which you see, and out of their substance will make other things and again other things... in order that the world may be ever new.

It never ceases to amaze me: we all love ourselves more than other people, but care more about their opinions than our own.

Remind oneself continually of one of those who practiced virtue in days gone by.

Observe constantly that all things take place by change.

Be cheerful, also, and seek not external help, nor the peace which others give. A man must stand straight, and not be kept straight by others.

We are born for synergy, just like the feet, just like the hands, just like the eyes, just like the rows of upper and lower teeth. Working against each other is unnatural, and being annoyed and turning one's back is counterproductive.

A good man does not spy around for the black spots in others, but presses unswervingly on towards his mark.
