I have so many messy moments.

I think we've all worked with that person at the office who takes themselves and their job so seriously.

I think it's a tough road if you're a stay-at-home mom, a working mom, if you have a partner, if you don't. It's the best job in the world, and the toughest job in the world all at the same time.

I have a special place in my heart for working moms - it's a constant pull on your heartstrings.

I love being a troubadour. I travel around the world with my wife and play little theaters. We have a ball.

Don't time travel into the past, roaming through the nuances as if they can change. Don't bookmark pages you've already read.

Rocket scientists agree that we have about reached the limit of our ability to travel in space using chemical rockets. To achieve anything near the speed of light we will need a new energy source and a new propellant. Nuclear fission is not an option.

I've always liked telling stories. That probably came from my dad, who definitely had the gift of gab and who wove a kind of personal folklore about his youth - stories full of adventure and ghosts and wild antics.
