Like the others here have said and I will stress it as well: Nothing matters until you get sales. Paying customers gives you a more defined value proposition for your product, it also tells you what specific niche to serve. A suggestion for Got #6. A very important piece of advice I received when I was working on my product was, "It's better to have 10 people love your product than 1000 who like your product"
