I've always been amazed at the different ways to make a buck that is safer and easier that the 'typical' way. Many people follow the herd like lemmings and go over the cliff together wondering how the entire herd could be so wrong,lol.
I noticed this technique at a Home Show years ago where hundreds of business have a stall and show off their supplies and installation services and hand out brochures etc. While walking through these many times I couldn't help notice one same guy making cash money hand over fist in the middle of the pack. All he was doing was selling hot roasted peanuts and a couple of things like that to the crowd as they walked through. He was the smart one in the pack as he couldn't help make money instantly regardless while many of these businesses didn't get the leads or sales they were hoping for in the 3 day Home show. Plus they were out their time and costs of the show. Those are the type of profitable trades I look for. Just a better way to skin the cat........
