For anyone wanting to teach their kids about the joys of starting their own business, a lemonade stand might not be the best way to go.I say this after my two boys, with encouragement from some neighborhood kids, were kicking around the idea of what to do on a lazy summer afternoon. Instead of riding bikes or playing video games – their usual mindless pleasures – it was decided they would start their own lemonade stand. Somehow our house was selected as the site.To give them full credit, they attacked this idea brimming with enthusiasm.
