In the 1991 comedy City Slickers, there’s a memorable exchange between the film’s protagonists, in which the older, sage figure tells the younger character, “Do you know what the secret of life is? One thing. Just one thing. You stick to that, and everything else don’t mean sh*t…. That’s what you’ve got to figure out.” Gary Keller (co-founder of the world’s most successful real estate company, Keller Williams Realty) teams up with his editor, Jay Papasan, to convince the world that this is the soundest advice out there, that to find and pursue that One Thing is the key to a life that is simpler, less stressful and more meaningful.
