I'm still learning about my swing more. I continue to learn, with the help of my hitting instructors.

I learned to canoe at summer camp and thought I'd pursue Olympic whitewater canoeing. In my senior year of high school, I instead decided to attend M.I.T. I like to say I've had only two jobs in my life: whitewater canoeing instructor and wilderness guide in college, and C.E.O. of iRobot.

Sarasota in 1974 was a city of 46,459 people, the 73rd-largest market in the country and sixth-largest in Florida, according to Arbitron Ratings. To supplement my meager salary, I was a bartender at Big Daddy's on St. Armand's Circle and a sailing instructor at nearby Lido Beach.

In karate, as your skill level increases, your instructor presents you with the next belt. But in poker, only you can decide when it's time to graduate to the next level. That's a tricky proposition for some players because it's difficult to assess your own progress.

Some golf instructors get overly technical and teach the mechanics of the ideal swing. That approach didn't work for me. So, I found a pro that didn't insist that I learn Tiger's swing. He accepted my physical limitations and improved my game by focusing on the minimal golf skills that I have.

Our approach to education has remained largely unchanged since the Renaissance: From middle school through college, most teaching is done by an instructor lecturing to a room full of students, only some of them paying attention.

You are overboard in deep open water without a PFD (personal floatation device), or at least that's what your instructor is yelling. Sink or swim, plebe.

My mindset is of the person who is still unsure whether they have enough money in their ATM to go to another bar. I lived that way when I was unemployed, when I was a snowboard instructor, and when I was at NYU. A lot of my personality is stuck in those five years, and I don't know if that's ever gonna change.
