Being cheerful keeps you healthy
Your own soul is nourished when you are kind; it is destroyed when you are cruel.
Under the Sun the race is not to the swift, nor the battle to the strong, nor bread to the wise, nor wealth to the intelligent, nor success to the skillful, but time and chance govern all. For man does not know his time.
All the rivers run into the sea; yet the sea is not full.
The man who walks with wise men becomes wise himself.
In much wisdom is much grief: and he that increaseth knowledge increaseth sorrow.
