There are books that teach, that we revere.
There are poems that we remember because they are true.
But there are only a few movies that show us how to live.

Just as the Don prepared Michael for his life, his words guide us as well:

"Don't raise your voice- Improve your argument."
"Never hate your enemies, it affects your judgment.
"Great men are not born great, they grow great."
"A man who doesn't spend time with his family can never be a real man."
"Accidents don't happen to people who take accidents as a personal insult."
"Time erodes gratitude more quickly than it does beauty."
"Never let anyone know what you are thinking."
"Forgive. Forget. Life is full of misfortunes."
And if that fails:
"Revenge is a dish that tastes best cold."

And when life serves us lemons, Clemenza offered us this:
"Leave the gun, take the cannoli."
