Research first. Do your research, do not jump into something without a deep dive into something that you have interest in. A lot of times these interest come from things that happen to you, and that's great.  Before you go diving into things I have a perfect example to share. I was competing with virtual private networks. So virtual private was a much better play because they were making money. They could sell where as I was free. I was stuck in the browser world which is free and I could not figure out how to make any money. So as I said do your research before you do anything.
