"Hey, I don't have all the answers. In life, to be honest, I've failed as much as I've succeeded. But I love my wife. I love my life, and I wish you my kind of success." -- spoken by the character 'Dicky Fox' in the film Jerry McGuire.
I have always felt lukewarm about Tom Cruise's film history. For every good one like Rain Man there is a bad one like Days of Thunder. However, Jerry McGuire is excellent, and this quote offers pretty good advice. I do not know about the 'wife' part of it because I have never been married, but the quote has some nice balance to it.
