Whether you run a Fortune 500 company or serve as CEO of your household, negotiating effectively is crucial to leading wisely and living well.

Leading and living are a series of constant negotiations. Consider what goes on during your typical week: Can you influence your client to accept your proposal? Will you persuade colleagues to give you the resources you need to finish your project? How will you ask your neighbor to switch carpool days so that you will finally have time to get to the gym?

According to conventional wisdom, a "win-win" outcome is the hallmark of success. However, until now, advice on getting there has overlooked one crucial element. It turns out that the most important negotiations you have, the ones that drive the impact of your leadership and the quality of your life, are the ones you have with yourself.

What does negotiating with yourself mean? It's what happens when you want to stay at the office, but also want to keep your promise to the family to get home in time for dinner. Or when one side of you votes to roll the dice and go for your dream job, while another worries about paying the mortgage. It's what you do when one part of you wants to give your relationship every chance to work, while another knows that this time it's really over.

When you're of more than one mind about what to do, negotiating with yourself is an essential skill. Should you say yes or no, or should you stall for time? Offer an olive branch or lay down the law? Speak your mind or hold your peace? When you know how to win the tug-of-wars inside of you, then you can "get to yes" in lasting and transformational ways.
