During my visit to the University of Vermont today I had lunch with seven talented Microbiology Ph.D. students. One of them asked me what was an important quality to have for achieving success in science. I said without hesitation, ‘Be curious’. It’s the answer I always give. Being curious is the first step to being a scientist, and it’s the quality you must always have to be a successful scientist. If you are not curious about the world around you and how it works, do something else.
