If you never had a dad, or your dad wasn't around, you probably missed this lesson. Many young boys have memories of skipping stones with their fathers. Maybe if you don't, that means that your father didn't know how to skip stones. There's no real point to it other than to do it, which is what makes it such a zen art form. I bet monks love skipping stones.
I feel like it's going to be a lost art as more people stay indoors for social media and videogames. When's the last time you just hung out at a creek? Trust me, it's super fun. People are much more imaginative than they give themselves credit for. Go to the creek, bring a ball, and you're set. You'll find something to do. You might not even have to use the ball.
