I'm here because I have a very important message: I think we have found the most important factor for success. And it was found close to here, Stanford1. [A] psychology professor took kids that were four years old and put them in a room all by themselves. And he would tell the child, a four-year-old kid, "Johnny, I am going to leave you here with a marshmallow for 15 minutes. If, after I come back, this marshmallow is here, you will get another one. So you will have two."
