What is the best piece of advice you've ever recieved in your life?

Some more international co-operation. We have so many agencies around the world. I think as soon as we start thinking as ourselves as citizens of Earth and not nations then progress in space will advance much more. Also a manned mission to Mars would be cool, I'd like to see a permanent settlement set up there or the moon like the prototypes drawn up in the 70's.

Arnold, out of all the careers and professions you've had. Which one holds the best memory and could you share that memory with us? Thanks!
