Los Angeles - Channing Tatum felt "messed with at school because he wasn't a very smart person".
The 34-year-old actor - who has suffered from attention deficit disorder (ADHD) and dyslexia - has hit out at the education system in the US for not helping him enough and simply "lumping" him into classes with Down Syndrome and autism suffers.
He said: "I have never considered myself a very smart person, for a lot of reasons. Not having early success on that one path messes with you.
"You get lumped in classes with kids with autism and Down Syndrome, and you look around and say, 'OK, 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. The system is broken. If we can streamline a multi-billion dollar company, we should be able to help kids who struggle the way I did."
Channing has 16-month-old daughter Everly with wife Jenna Dewan-Tatum and while he admits he loves spending time with the little one, he is glad to get some peace and quiet at night when he puts her to bed.
Speaking to T magazine, he added: "You notice your behaviour, like, 'Wow, I don't have much patience right now. Why is that?'
"You spend the day watching this thing constantly taking in information, and you have to be sure you're making that happen.
"At the end of the day when I put her to bed, I feel glad to have some peace but say to myself, That was so much fun."
