We have to remain humble about our understanding of the brain, because even our most powerful tools remain pretty blunt instruments for decoding the brain. In fact, we still do not know how to decipher the basic language of how the brain works.

My philosophy is really based on humility. I don't think we know enough to fix either diagnostics or therapeutics. The future of psychiatry is clinical neuroscience, based on a much deeper understanding of the brain.

Sometimes, patients with serious mental illness, just as with other serious medical illnesses, require hospitalization. In the absence of available public or private hospital beds, there are few options.

For bipolar in adults, I think there's pretty good agreement about what this looks like. For bipolar in children, there is some considerable debate about where are the boundaries. At the mild end, are these just kids who are active? Is this the class clown at the very severe - is this something other than a mood disorder?

I'm super grateful that there wasn't social media when I was a kid, but that sort of self-doubt crept in at a young age. It's bullying. It's the comments here and there, and maybe somebody says something to you that they don't even mean to be a mean-spirited comment, but they'll just kind of say it to you in passing.

I hated science in high school. Technology? Engineering? Math? Why would I ever need this? Little did I realize that music was also about science, technology, engineering and mathematics, all rolled into one.

I see robotic technology getting rid of the dangerous, the dirty, and the just plain boring jobs. Some people say, 'You can't. People won't have anything to do.' But we found things that were a lot easier than backbreaking labor in the sun and the fields. Let people rise to better things.

The music business has changed incredibly. There used to be 50 record companies. Now there's only three, and it's just getting smaller and smaller. But then again, you have the Internet, so anybody who has music can get it out there.
