By Dr. Seuss
Dr. Seuss's rhyming send-off into a big, bumpy life, handed over at graduations and first days to tell a child they're headed somewhere good.
A small figure sets off through Seuss's tilting, candy-colored landscapes, and the book talks straight to the child the whole way: you have brains in your head and feet in your shoes, you can steer yourself any direction you choose. It promises the high, soaring days, then spends real time on the low ones — the slumps, the lonely stretches, and the maddening Waiting Place where everybody just sits around waiting for something to happen. After that it gets the child moving again and climbing back up. This is the one people hand out at graduations and every fresh start.
People give this for a threshold — the last day of one thing, the first day of the next. What lifts it above the usual you-can-do-it pep talk is that it spends real time on the setbacks before it cheers. It names the slumps, the lonely days, the times you get left in a lurch, and only then insists the child will keep going anyway. That's a braver thing to hand someone than 'everything will be easy,' and it's why people write in the front cover and keep the book for decades.
