The piano is a universal instrument. If you start there, learn your theory and how to read, you can go on to any other instrument.

There are really three parts to the creative process. First there is inspiration, then there is the execution, and finally there is the release.

David Lee Roth had the idea that if you covered a successful song, you were half way home. C'mon - Van Halen doing 'Dancing in the Streets'? It was stupid. I started feeling like I would rather bomb playing my own songs than be successful playing someone else's music.

I destroyed a lot of guitars trying to get them to do what I wanted, but I learned something from every guitar I tore apart, and discovered even more things. Things like if the string is not straight from the bridge saddle to the nut, you're going to have friction.

I have pictures of me sitting in the racquetball court in my pajamas with an acoustic guitar, and Wolfgang is probably just two-and-a-half-feet tall. I'll never forget the day I saw his foot tapping along in beat! I knew then, I couldn't wait for the day I'd be able to make music with my son. I don't know what more I could ask for.

I'm blessed with a good pair of ears. That's how I fooled my piano teacher. I'd watch his fingers and I'd listen to it, and I just kind of basically learned it by myself.

It's funny, when bands or younger musicians ask me: 'So, what does it take to make it?' Well, first explain to me what you mean by 'making it': Do you want to be a rock star or do you want music to be your livelihood?

There's a plaque on our wall that says we've sold over 65 million albums, and I don't feel I've accomplished anything. I feel like I'm just getting started.

We make music for a living. Like I've always said, if you like what you're doing, you're halfway there; if someone else likes it, that's even better. If they don't like it, at least you like it. Not to be selfish, but you kind of have to be.

A good producer brings out the best in the artist he's working with. You shouldn't be able to listen to something and say, 'So-and-so produced this album.'

Actually, if I could deliberately sit down and write a pop hit, all my songs would be pop hits! Let's put it this way. I play what I like to hear. And sometimes I like to hear something poppy, and sometimes I don't.

And if I would have taken lessons I probably wouldn't have done it, and what forced me to do all this weird stuff on the guitar was I couldn't afford effects pedals, I didn't have all this stuff when I was a kid so I just tried to squeeze all the weird noises I could out of the guitar, which brings me to building guitars.

Before the operation on my left hand I wasn't able to stretch my fingers open all the way. I've never had very big hands, but I could do the splits with them. Eventually I couldn't any more. I had a twisted tendon in my little finger that prevented me from being able to stretch.

Cancer is like a cockroach. It just comes back stronger. I'm tearing apart the immune system of the cockroach and seeing how it ticks. I've opened up my own pathology center.

Every song is like a kid. How can you have that many kids and have a favorite? Which one do I like to hang most with? Probably the one that I haven't hung most with recently.

Everything I did is because I wanted to do it. If I weren't playing this arena, if I were playing a club, I'd still be doing it because that's what I want to do. I love playing the guitar.

'For Unlawful Carnal Knowledge' took a year to record; that's why the playing on it might sound somewhat labored. 'Balance,' on the other hand, was written and recorded in only four months, so the whole process was quicker and more immediate.

I can't read music. Instead, I'd do stuff inside the piano, do harmonics and all kinds of crazy things. They used to put me in these annual piano contests down at Long Beach City College, and two years in a row, I won first prize - out of like 5,000 kids!

The judges were like, 'Very interesting interpretation!' I thought I was playing it right.

I don't feel a day older when it comes to my approach to music or what gets me off than when I was a teenager. I've always been into different kinds of stuff and when I play I like to play loud. I like my arm hairs to move and I like my body to vibrate 'cause I like the feel of it; I'm still a teenager at heart.
