Do you remember the movie, City Slickers?  Jack Palance played the sometimes scary cowboy named Curly, and Billy Crystal as the city slicker [Mitch] looking for perspective on a dude ranch vacation.  At one point, Curly asks Mitch - Do you know what the secret of life is?  Seeing that Mitch is puzzled, Curly holds up one FINGER and says THIS!  The incredulous Mitch says, “Your finger is the secret to life?” Curly responds, “One thing; just one thing!  You stick with that and the rest just don’t matter.” The inquisitive Mitch asks, “But what is the one thing?”  Curly smiles and responds, “That is what you have to find out.”
