What would be your best tip to future space travelers about how to prepare for living and working in space, particularly those who may not be career astronauts?

Guess basically my question is, is there anything important that Tom Cruise needs to know?

I think if people are gonna come to space, um, and not be career astronauts, I think the biggest tip you could have is to be organized, because if you're not organized, you're gonna lose your stuff in no time flat, and you will.

That will make life really hard.

So you've got to be well organized to be in space.
