One of my favorite memories from growing up in Brazil is being in the kitchen with my family and watching everyone bake and cook.

Growing up eating fruits and vegetables fresh from our farm added a lot to the way I taste and look at food today, and I wanted the same for my kids and other kids.

My waist used to be tiny. I just saw a picture of Miley Cyrus with a little crop top and low pants, and I'm like, 'That was me growing up in Brazil!' I had the typical model body, but after babies, it changed. I look more like a woman.

I'm still learning how to do things - like lining my eyes? Forget it.

During its first year of operation, Florida Virtual School had 77 students. The next year, it had 476 students; then 2,489 students the year after that.

Believe it or not, one teacher used to call me a giant spastic for not being able to play football.

I loved doing problems in school. I'd take them home and make up new ones of my own. But the best problem I ever found, I found in my local public library. I was just browsing through the section of math books and I found this one book, which was all about one particular problem - Fermat's Last Theorem.

It's always extremely interesting to speak at colleges. My books are taught in many colleges in America and are part of the educational system, so it's really important to me. I don't believe in so many things in life, but something I believe in is education.
