During the day you should behave in such a way that you can sleep at night in peace; and in your youth you should behave in such a way that you can live in your old age in peace.
Every time you wake up and ask yourself, “What good things am I going to do today?” remember that, when the sun goes down at sunset, it will take a part of your life with it.
You should acquire the kind of wealth which cannot be stolen from you by thieves, which people in power cannot take from you, which will stay with you even after your death, never diminishing and never disappearing. This wealth is your soul.
Being poor is better than living in luxury and serving the rich. Do not stand at the door of a rich man asking for favors if you hope to lead a good life.
