I was diagnosed with attention deficit hyperactivity disorder (ADD/ADHD) and obsessive-compulsive disorder (OCD) as an adult, but I don't remember a time when I didn't have them. Back in the 1960s, when I was growing up, my symptoms didn't have a name, and you didn't go to the doctor to find out.

I'm always in a hotel room, and I spend a good portion of my day setting it up so it's comfortable for me. Whether that means making paths out of towels so I don't touch the carpet or removing the comforters or just not touching things. Even sitting on a plane with a bunch of other people - it's really hard for me.

I once called construction companies to bid on an addition to the school library so that there would suddenly be people outside, measuring the building. 'Who authorized this?' the principal would ask. The answer: 'Howie Mandel.'

I once missed an appointment because I left my house, I locked the door. And then I thought, like anybody else, you know, 'I don't think I locked the door.' I just kept going back to the door. And I couldn't stop myself from checking and checking.

Where I'm at in my relationship with my wife or my family and life in general, I feel like it all comes out in the music. Hopefully, it's always there, but in an ambiguous and abstract way and not real straightforward.

Most kids just follow the cycle. My grandfather didn't finish high school. My father didn't, and I didn't. But you can break the cycle. You can have a successful marriage and be a good father.

I don't want to be too strict, because I think kids can get rebellious, but I want to raise my daughter to be passionate about doing good things and pursuing real things and hobbies instead of frivolous materialistic stuff.

I grew up completely alone but with all the comforts of knowing I had a cushioning family structure around me - and yet I could free myself from it.
