4 Steps to the Epiphany by Steve Blank did the trick for me, but a lot of people find it too detailed/boring. There's an ebook at custdev.com that's meant to cover the same content in a more accessible way, but I don't think it's a good starting place since it assumes you have some knowledge about the concepts. Just googling around and digging into "customer development" is probably a safe starting point, and then grab Steve's book if it resonates w/ the way you think.
