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.

What I've learned in life is that you can't always win, especially in sport, but you can be a true champion for everything you did to get there.

I learned something through the experiences in my life, and that is that you never judge how someone may be reacting to a situation because you don't know what they may be going through. It's important that you treat people well, and I try to make people feel good about themselves always.

If people have the choice of where they settle in Europe, then we cannot be surprised that they choose to come over here in search of a better life.

I have to say that it was a very strange experience when, later in life, I represented Byron Scott and was negotiating with West - whose picture I used to have over my bed! That took some getting used to.
