I find the difference, for me, between having no money and having quite a bit is that the bills get bigger. And that's it. The lifestyle doesn't change.
Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the drug store, but that's just peanuts to space.
I remember some stories had a very big impact on me, likeThe Little Train That Could,which is about the importance of not giving up, andLittle Toot,about a playful tugboat in the New York harbor.
