I've been writing about growing old for some time, really from the beginning of my career. It's something I'm apparently hung up about and now that I am old, hopefully I speak about it with some authority.

When you start your career, you have to figure out a way to separate yourself from the pack. So I went for a kind of preppy, psycho-killer look: I had short hair, grey flannel pants, and a button-down shirt. I think it worked, because nobody else was looking that way at that time.

I have travelled and been pretty much a one man operation for most of my career, and I think it'll continue to be that way.

I've never really suffered complete and utter writer's block, really. I equate it with sex: in the beginning of my career, I was writing five songs a week; now, I occasionally write a song. But it's an exciting moment when it happens!

You do your work, and you do the best you can. That's what my parents taught me, and I think what they were saying was, 'If you do a good job, other things may come your way.' That's really been the way my career has unfolded throughout the years.

A little secret about actors is that we never think we do a great job in auditions. We kind of just go in and do our work and leave sort of hoping for the best. It's an interesting dynamic - acting is such an interesting job. You never quite know how well you do.

You look at most artists, the arc of their career, there's a definite decline at the end. And that decline could set in at any time. In your 50s, or your 60s and 70s if you're lucky. Time goes by fast, and you've got to be busy all the time.

Starting a company in San Francisco when we did usually meant it was destined to be a data-driven tech company. But that didn't seem to fully encompass what we wanted with Airbnb. When we tried looking through a tech lens, it didn't work. The humanity was missing.
