Two brothers, one notebook, a lot of crayons.
A few months ago, my oldest asked me what a business is. I told him: a business is when you make something people want and they pay you for it. He thought about it for three seconds and said, "I want to make coloring books."
Their first book was for Mother's Day — flowers, hugs, breakfast in bed, a "World's Best Mom" certificate. Real people bought it. They watched the dashboard go from $0 to actual money. They learned what a business is.
Now they're building the Summer book, the Fall book, and whatever comes next. Every page, hand-drawn at the kitchen table.
