He who is not contented with what he has, would not be contented with what he would like to have.

Contentment is natural wealth.

Prefer knowledge to wealth, for the one is transitory, the other perpetual.

I just thank God I don't live in a trailer.

We suffer a lot the few things we lack and we enjoy too little the many things we have.

Give thanks for what you are today and go on fighting for what you gonna be tomorrow.
