One thing that was very important to me was that I felt comfortable in the lab from being very, very small. I knew that that's where I belonged, and I could fix things and move things. And no matter how many classrooms I went into where I was the only girl in the physics class or whatever, I never questioned the fact that I didn't belong there.
One thing I've learned through all the ups and downs is that if you're doing things right, then you have a core group of people. Not just a core group like your homies or your buddies, but a group of people that has a good influence on you, who you respect and admire, and you know that if they're on your side, you're doing something right.
