After "flipping" (for two hours) through this book, my kids (9, 7, 6) started pulling our cardboard boxes and making signs for their "lemonade stand". They also started thinking and analyzing how many people pass by hour house on a daily basis, and if at least half of them bought the water bottles, how much "profit" they would rake in.
As a parent, I don't want to raise men with a mindset for a 9-5 job but rather offer a wide array of opportunities for their futures, and IF they choose the 9-5 job, at least they knew what their options were.
