You can find bacteria everywhere. They're invisible to us. I've never seen a bacterium, except under a microscope. They're so small, we don't see them, but they are everywhere.
We mostly don't get sick. Most often, bacteria are keeping us well.
Everybody, as soon as they do a good experiment, their first thought in this lab is, 'That can't be right. I must have screwed it up. What did I do wrong?' And that's the best kind of scientist because they're filled with this self-doubt. And if I'm going to be honest, that's who I am. And it's what drives me.
Science is difficult and slow no matter who you are. The hours are long, and the glorious 'aha' days come only very infrequently. You have to keep believing that if you put in the hours, those days will indeed come!
When antibiotics became industrially produced following World War II, our quality of life and our longevity improved enormously. No one thought bacteria were going to become resistant.
