“I was only kicking down the Christmas tree to get the star on top.”

“Stand at the top of a cliff and jump off and build your wings on the way down.”

“Ask for no guarantees, ask for no security, there never was such an animal. And if there were, it would be related to the great sloth which hangs upside down in a tree all day every day, sleeping it's life away. To hell with that," he said, "shake the tree and knock the great sloth down on his ass.”

“Where would you like to go, what would you really like to do with your life? See Istanbul, Port Said, Nairobi, Budapest. Write a book. Smoke too many cigarettes. Fall off a cliff but get caught in a tree halfway down. Get shot at a few times in a dark alley on a Morrocan midnight. Love a beautiful woman.”

“When I was a boy in the midwest I used to go out and look at the stars at night and wonder about them.I guess every boy does that.When I wasn't looking at the stars, I was running in the my old or my brand-new tennis shoes, on my way to swing in a tree, swim in a lake, or delve in the town library to read about dinosaurs or time machines.I guess every boy has done that, too.This is a book about those stars and those tennis shoes. Mainly about the stars, beacuse that is the way I grew up, getting more and more involved with rockets and space as I moved toward my twelfth, thirteenth, and fourteenth years.Not that I have forgotten the tennis shoes and their powerful magic, as you will see in the last story here, which I have included not because it concerns the future, but because it gives you some sort of idea of the kind of boy I was when I was looking at the stars and thinking of the years ahead.Nor have I forgetten the dinosaurs that all boys love; they are here, too, along with a machine that travels back in time to step on a butterfly.This is a book then by a boy who grew up in a small illinois town and lived to see the space age arrive, as he hoped and dreamt it would.I dedicate these stories to all boys who wonder about the past, run swiftly in the present, and have high hopes for our future.The stars are yours, if you have the head, the hands, and the heart for them.”

“Doom. Doom. You sound like a funeral bell tolling,' said Grandfather. 'Talk like that is worse than swearing. I won't wash out your mouth with soap, however. A thimbleful of dandelion wine is indicated. Here, now, swig it down What's it taste like?''I'm a fire-eater! Whoosh!''Now upstairs, run three times around the block, do five somersets, six pushups, climb two trees, and you'll be concertmaster instead of chief mourner. Get!'On his way, running, Douglas thought, 'Four pushups, one tree and two somersets will do it”

“I got a statistic for you right now. Grab your pencil, Doug. There are five billion trees in the world. I looked it up. Under every tree is a shadow, right? So, then, what makes night? I'll tell you: shadows crawling out from under five billion trees! Think of it! Shadows running around in the air, muddying the waters you might say. If only we could figure a way to keep those darn five billion shadows under those trees, we could stay up half the night, Doug, because there'd be no night!”
