I used to live near the beach and a neighbor had one of those little sunfish sailboats and it was resting at the water's edge. She told me I could take it out if I wanted but I wasn't interested in sailing that day so I just started goofing around on it mostly because she was kinda hot
Being a surfer and the fact a Sunfish is about nine foot long I tried standing up on the sailboat like a surfboard and then tried to make it go by holding onto the sail. I remember telling her " Hey, look at me I'm a sail surfer ". I couldn't get the thing to go because there was no way to hold onto the sail and also let it catch the wind. I remember telling her that it needed some kind of bar across the sail so I could hold it sideways. We shrugged it off and didn't think anymore about it.
About eight years later the first Windsurfer appeared on the market and it was essentially just what I had talked about on that day. There were a lot of people on the beach that day and I can imagine somebody sitting on a beach chair watching what I was doing, taking the inspiration and had the ability to turn it into a world wide sport.
I'm sitting on something right now that could be unbelievably huge but life continues to throw me so many curve balls I haven't had the chance to hit it out of the park.
