@Nunzio Presta there are many articles out there about the mistakes entrepreneurs make (usually within their first year). I've come across three or more on Entrepreneur.com alone. One that stood out to me the most was this one by Timothy Skyes. It's simple and gets straight to the point. It's surprising the mistakes have been so common throughout the years. One thing I would add is, "Not doing your research." It sucks to jump into something just to fall flat on your face. Prepare yourself for all situations you can possibly think of before jumping. That way if you fall, at least you're wearing knee pads and a helmet!
