21 Jump Street actor Channing Tatum, who plays Mark Schultz in the upcoming Foxcatcher, dealt with ADHD and dyslexia growing up.

“I have never considered myself a very smart person, for a lot of reasons,” Tatum recently told The New York Times’ T magazine.

Tatum, who found his groove as a real-life stripper at a Florida club called Male Encounter before entering the acting scene, had trouble adjusting to school.

“Not having early success on that one path messes with you,” he told the magazine. “You get lumped in classes with kids with autism and Down syndrome, and you look around and say, ‘Okay, so this is where I’m at.’ Or you get put in the typical classes and you say, ‘All right, I’m obviously not like these kids either.’ So you’re kind of nowhere. You’re just different.”

Although Tatum says he performed better at school after being put on medication, he’s confident that he’d never give his one-year-old daughter Everly medicine to help her focus because of the ill-effects it had on him. “I was on it, but it made be a zombie,” he admitted.
