After years of active research, Marc now talks, writes, and blogs about the science and experience of addiction and how people outgrow it. Visit his website here.

Over dinner a couple months ago, one of my friends said he needed some help coming up with a name for a new website. He told me a bit about the site and asked if I could help think of something over dinner.

One the best pieces of advice my mentor gave me many years ago was, "When you are in conflict with someone, don't push back." As a young professional, I was shocked and more than a little frustrated. What did that mean? What if I can't defend myself when someone says something wrong about me?
