I exercise at home - light cardio and yoga.

When you do take the home pregnancy test, it doesn't quite seem real. But when you see the baby and the heartbeat on the ultrasound, it's so incredible.

My message is: You don't have to give up being popular, fun, or fashionable in order to be smart; they can go hand and hand. Doing math is a great way to exercise your brain; being smart is going to make you more powerful in life.

In high school, a teacher once suggested that I be a math major in college. I thought, 'Me? You've got to be joking!' I mean, in junior high, I used to come home and cry because I was so afraid of my math homework. Seriously, I was terrified of math.

Students never think it can be the teacher's fault and so I thought I was stupid. I was frustrated and would come home and cry because I couldn't do it. Then we got a new teacher who made math accessible. That made all the difference and I learned that it's how you present it that makes it scary or friendly.

But yoga is helping a lot, at the end of exercise you are a relaxed person.
