The 2011 TIME 100

I have to admit that as I made my way to meet Mark for the first time, I didn't really know what to expect. We were meeting for a business lunch to discuss working on a project together. As he entered, he seemed pretty much as one would assume: good-looking, a commanding presence, and a casual swagger that can only be associated with true confidence. But what began to unfold as I talked to him was a sincere conversation that brought forth his deeper character. He was insightful, instinctual and extremely funny. My favorite thing about Mark, 39, is that he is genuine. He shares his true self through his work, through his philanthropic efforts and through his commitment to all of his endeavors. Mark never shies away from the truth. I have seen firsthand the way he puts people at ease with his honesty, because people will always respond to truth. Mark is a powerhouse. He has a work ethic that is incomparable. He is where he is because of his hard work, his talent and his sheer force of will. I have no doubt that he can and will accomplish anything he sets his mind to. I can't wait to see what's next.
