    Many students have trouble sitting quietly. They play with pencils, talk out of turn, and jump to do things before thinking. Others can sit still but find it hard to focus on classwork. They may daydream, struggle to organize their work and forget to do assignments.

Most people feel restless or unglued from time to time, but some feel this way almost all the time. Nearly one out of ten kids have ADHD ( Attention-Deficit /Hyperactivity Disorder ). But ADHD does not have to be a roadblock to achievement. Here, two professionals in their fields share the secrets of their success.

Astronaut Scott Kelly has flown on four space tasks, including one that lasted close to a year. But when he was growing up, he had trouble focusing in school. As a result, he earned low grades. I read a novel in college about the space program. The book motivated me to study harder and become a much better student and eventually, an astronaut. The lesson I learned was: Don’t give up on yourself. Find something or someone that motivates you and use that to help motivate yourself.

Figure skater Zachary Donohue placed fourth for ice dancing at the 2018 Winter Olympics. In elementary school, Zachary had a hard time making friends because his classmates thought lie was wild, overly excitable and lacking orderly continuity. “A lot of very successful people have ADHD, so wear it with pride. When I was 16, I realized that it was OK for me to be different than others. Now, at 27, I’m learning to understand my own feelings. I still struggle with ADHD, but I’ve learned that I’m responsible for more than just myself. I’ve learned how important it is to be organized and to be a step ahead. “
