Another way of saying "do the homework" is "exercising due diligence". If you don't value your invention enough to give it it's due, then you will fail. I did not say MAY fail, I said WILL fail. This is why ideas are viewed as a dime a dozen. I am surprised at how many inventors invent things just because they had an idea. They have no idea whether there is a need for their invention, or even a strong demand, but because their wife, brother, cousin, friend think it's a good idea...well gosh darn it, it's my ticket to the big time. The more I listen to Roger, the sharper I become...not because I view Roger as the "guru", but he has been down the inventing path so many times, he has a very pragmatic approach...AND he looks for the NEED...or asks for the need...AND then he invents.
