I have this vintage Harley-Davidson motorcycle jacket. When I put it on, it has this supercool feeling to it.

I believe in the limitlessness of humans. We're capable of incredible things. At times, that realization is frightening.

Adam Levine and I remade the Rolling Stones' classic Wild Horses, and it is right up my alley, that whole style. It has a style of its own but still stays very true to the classic arrangement, and I love it.

I don't have a ton of friends, but the friends I have are great ones. I don't have huge family, but the family I have is a great one.

It's not until I hear songs that I've done, that I realize how much of an inspiration music from the '60s and '70s has been.

Failure isn't an option. I've erased the word fear from my vocabulary and I think when you erase fear you can't fail.

Things can be really empty in this world, and I don't just mean the music world. It can become a very meaningless place if you don't really understand: Who am I? Why am I here? What am I doing? To feel fulfillment and have a deeper level of understanding, personally, that is the most important thing.
