Do not shorten the morning by getting up late, or waste it in unworthy occupations or in talk; look upon it as the quintessence of life, as to a certain extent sacred. Evening is like old age: we are languid, talkative, silly. Each day is a little life: every waking and rising a little birth, every fresh morning a little youth, every going to rest and sleep a little death.

Money is human happiness in the abstract.

We must set limits to our wishes, curb our desires, moderate our anger, always remembering that an individual can attain only an infinitesimal share in anything that is worth having; and that on the other hand, everyone must incur many of the ills of life

It is only a man's own fundamental thoughts that have truth and life in them.

Genius and madness have something in common: both live in a world that is different from that which exists for everyone else.

Every satisfaction he attains lays the seeds of some new desire, so that there is no end to the wishes of each individual will.

For our improvement we need a mirror.
