I often think back to why I came to MIT, especially when the semester gets tough. I remember I came to the admitted students weekend and toured one of the dorms. The walls were covered with murals and the floors with junk --- motors, robot parts, circuit boards. People had built their own lofts; someone had rigged their door to open automatically when it recognized them. Someone had hooked up a camera and a projector so that you could "draw" on one of the nearby buildings with a laser pointer.<p>So of course, I came to MIT. I remember discovering pg's essays around sophomore year and starting to consider starting my own company, but my transformation really began when I set foot here at MIT, where creative and curious people build mind-blowing things every day.<p>At first it's intimidating. These people all seem so smart! Who am I to build a roller coaster, paint a 20 foot mural, build a loft, hack a PS3, build a crazy device and start a company out of it? You hear about these things in the abstract and you're intimidated. But then you get home and see people building a roller coaster in your courtyard and you realize: Who am I <i>not</i> to do awesome things? Life is too short, damn it. It seems obvious to the entrepreneurially minded, but it's hard to describe the impact it had on me. I could've learned the same course material in many other places. But I cannot overstate how powerfully this cultural immersion changed my life.
