I'm realizing just how naive it was the further I get in the process :) Definitely a lot of challenges I hadn't expected and a lot of mistakes I've already made even this short of time into it. The biggest has been not doing enough research into my target market and application. Right now it's looking like my original idea isn't going to be a viable product, so I'm going to be switching to a new application idea, this time with much more research involved.
