You know, I do music. If you look under the hood of the industry I'm in, it's all based on technology. From radio to phonographs to CDs, it's all technology. Microphones, reel-to-reels, cameras, editing, chips, it's all technology.

The only colour I see is this wonderful green and blue planet.

I can't sing “I Believe I Can Fly”. I sing that horrible. But I can sing “I Gotta Feeling” good. I wrote it for my capabilities. So I Gotta Feeling is just about let me make a song to inspire people to have a good time.

Traveling in Europe made me understand that America has an island mentality: No one exists except us. There's a whole other world out there, but most Americans - all they know is America, the marketing plan.

There are five issues that make a fist of a hand that can knock America out cold. They're lack of jobs, obesity, diabetes, homelessness, and lack of good education.

There are no problems that can’t be solved. The world is too full of options. If you can’t solve the #problem, it’s because you haven’t found the right option ... But the answer is always there.

If my mind's not trying to fix something or create something, I don't know what to do. It just throws me off.
