Just stop collecting information and start creating. It sounds overly simplified but that's what it will ultimately boil down to. If you want to get into specifics of your situation, please feel free to contact me directly.
Matthew - I imagine most of us can relate to your situation - and the good news is, it's a normal problem. What you need to do is to start blending some action with your dreams. Decide what the next step is, something you can do today, and do it. Taking small steps has a way of turning a dream job into real job. I would also second Rob's advice (and take him up on his offer to talk specifics with you). And my friend and fellow 48days member, Adam Suter, wrote a great book that would be helpful, Vision ADD: From Ideas to Work That Matters.
Keep us posted!
Oh my gosh Matthew, what a great problem to have! :) That's what I LOVE about the 48 Days community, folks don't care a bit to offer great advice and resources, for free! And it does create a bit of info overload, but I think it is AWESOME! Robert and Chet have given good advice though. So yeah, don't get bogged down with to much info. As far as 48 Days .net goes, I usually tell folks to utilize the "search" option. Put the key words in and it will usually pull up what you are looking for to answer your questions.
I love your question, Matthew, you rock!
