Achieving something that's important to you: That's probably a big reason you're listening to this podcast. But what is it about success that drives us? Do we achieve for its own sake, or is there something more?

That's what Marshall Goldsmith is exploring. He's one of the most recognized thinkers and writers on the topic of leadership, but in his latest book, "The Earned Life," he asks: Why are we doing all this? Does success really make us happy? And what if those two things were not so deeply connected?

Whitney and Marshall sit down for a conversation that turns traditional Western views of success and happiness on their head. He notes that some of the most successful leaders are great at delaying gratification, only to look back on what they missed out on in life. In fact, after we accomplish something great, we should stop expecting more, but default to a new beginning.
