From the greatest to the smallest, happiness and usefulness are largely found in the same soul, and the joy of life is won in its deepest and truest sense only by those who have not shirked life's burdens.
There is a difference between happiness and wisdom: he that thinks himself the happiest man is really so; but he that thinks himself the wisest is generally the greatest fool.
The Life of the intellect is the best and pleasantest for man, because the intellect more than anything else is the man. Thus it will be the happiest life as well.

Love, compassion and concern for others are real sources of happiness. If you have these in abundance, you will not be disturbed even by the most uncomfortable circumstances. If you nurse hatred, however, you will not be happy even in the lap of luxury. Thus, if we really want happiness, we must widen the sphere of love. This is both religious thinking and basic common sense.
