I mentioned Richard Feynman in my last post. For those who don’t know the name, Richard Feynman was one of the world’s greatest scientists. He was a physicist – not very glamorous you might say, but here is a video of him explaining the nature of light. It doesn’t matter if you can’t understand it all exactly – what matters is his infectious enthusiasm. If you can have the same enthusiasm about your job that Feynman obviously has here, then you are very fortunate indeed.
