concept paper overload

Seems that I have more ideas without the time, knowledge base, assistance, and money to carry them all out in terms of this concept proposal. As I work on one idea, it seems to take a turn to another idea, and then another. So I bounced the ideas out to a few fellow employees who didn't help clarify my decisions, but added more suggestions to the mix. As I review what I have written thus far, I can't help but feel more overwhelmed. I think it is time to eliminate alot of the plan, and just focus on one or two smaller ideas. I am wondering how everyone else is doing.
