Rabbi Ben Zoma was asked:
"Who is wise?"
"He who always finds something to learn from others," said the Rabbi.
"Who is strong?"
"The man who is capable of dominating himself," responded the Rabbi.
"Who is wealthy?"
"He who knows the treasure he has: his days and hours of life, which can change everything which goes on around him."
"Who deserves respect?"
"He who respects himself and his neighbor."
"These things are all so obvious," commented one of those present. The Rabbi concluded by saying:
"That is why they are so difficult to observe."
