It's very hard to be honest. I have always thought about ideas without actually doing anything (either talking with people about it or actually implementing it). I don't know why I'm like that, maybe because I'm new to all of this. Takes a step back and sighs.

Absolutely agree. If you don't know where to find your target market, then you probably haven't communicated with them.

If you haven't communicated with them, then how do you know that the problem is actually a problem? Even if it is a problem, how do you know your solution addresses it? How do you know you understand the problem well enough to have actually solved it without creating other, bigger problems?

If you don't know where your customers congregate, or have a way to get in touch with them, how are you going to sell it? I can tell you that it's the VERY rare startup that you can just put online and get customers. Even if it gets covered by tech blogs (which are generally the startup coverers) how do you know if it's reaching your target market?
