According to Pastor Rick Warren -- bestselling author of The Purpose Driven Life -- everybody lives at one of three levels in life: survival, success and significance. In this clip from "Oprah's Lifeclass," Pastor Warren says that most people, in fact, live at the "success" level -- in other words, they live a comfortable life, have a roof over their heads and, for the most part, have what they want. Yet they still feel unsatisfied -- and can't figure out why.

"Now, society defines success as looking good, feeling good, and having the goods," he says. "We call that 'the good life.' Looking good, feeling good, having the goods. The only problem with the good life [is] it’s not good enough. Because I meet people all the time who say, 'Well, if I’m so successful, why do I still feel, like, unsatisfied?'... And the truth is, we’re made for more than a good life. We’re made for the better life."

Tune in to Pastor Warren on "Oprah's Lifeclass" at 9 p.m. ET on Sunday, on OWN.
