What are the vales learned in reading about Heracles?

Like so many Greek characters, I think that one of the
most powerful values grasped from the myth is the idea of humility.  Even though
Heracles is blessed with superhuman strength, he is not able to act without regard or
reverence for the powers of divinity.  The fact that he has to pass through tests that
are designed to humble him despite his extraordinary strength would reflect this.  Along
these lines would be the value of everyone having to endure suffering and challenge. 
Heracles' strength does not absolve him from feeling pain, from experiencing suffering,
and from not having to endure significant regret for his actions.  While he might
possess the brawn of a god, Heracles' plight reminds the reader in the most painful of
ways that he is "only human" and must endure what all humans have to
endure.
