The man with a host of friends who slaps on the back everybody he meets is regarded as the friend of nobody.

But a man's best friend is the one who not only wishes him well but wishes it for his own sake (even though nobody will ever know it): and this condition is best fulfilled by his attitude towards himself - and similarly with all the other attributes that go to define a friend. For we have said before that all friendly feelings for others are extensions of a man's feelings for himself.

Money is a guarantee that we may have what we want in the future. Though we need nothing at the moment it insures the possibility of satisfying a new desire when it arises.

Every art and every inquiry, and similarly every action and pursuit, is thought to aim at some good; and for this reason the good has rightly been declared to be that at which all things aim.

It is clear that those constitutions which aim at the common good are right, as being in accord with absolute justice; while those which aim only at the good of the rulers are wrong.

No great mind has ever existed without a touch of madness.

The most important relationship we can all have is the one you have with yourself, the most important journey you can take is one of self-discovery. To know yourself, you must spend time with yourself, you must not be afraid to be alone. Knowing yourself is the beginning of all wisdom.
