"My advice is to do something which interests you or which you enjoy...and do it to the absolute best of your ability. If it interests you, however mundane it might seem on the surface, still explore it because something unexpected often turns up just when you least expect it. With this recipe, whatever your limitations, you will still do better than anyone else. Having chosen something worth doing, never give up and try not to let anyone down." Harold Kroto's advice to schoolchildren in 2001.
"If you make people think they're thinking, they'll love you but if you really make them think they'll hate you." Don Marquis (Harold Kroto said this was his favorite quote, when giving the 2006 Charles Simonyi lecture: Can the Internet Save the Enlightenment?)
