Try thinking more broadly about applications for the technology. Find a situation where there is a guy who is looking for a solution to his problem at least as hard as you're looking for a customer for the product. Don't try to convince a bunch of people who don't seem to want to be convinced, that is a really painful process that leaves you disillusioned and makes you wonder if you should quit. Find one of the few guys who is going to love you when he sees your stuff. And if your stuff works for him, he'll probably help you expand. Bottom line: spend more time thinking about applications and finding people, and less time trying to convince them
