Just do the research. You know so many people who have an idea get excited, and they automatically turn to marketing. They start spending money on marketing. I would strongly suggest you do the research. Identify if your product or service has competition or is it innovative? Look and see what other people are doing. What niche do you fit into? Where do your customers hang out at? Those are just some small things to really start thinking of before you just automatically start jumping into trying to make money.
