That's the question I am trying to answer every day. Here are some of the other questions that often pop up at the same time....
What would that cool new thing be? If I did come up with something how many should I make and how should I make them? How much would it cost to make them? How much time would it take me? How many steps would be involved and can any of them be eliminated? Is there a better way to make this thing? Is there a cheaper way to make it? Is there an element that would give it something extra and would that be worth considering? What if it doesn't fly, then what?
So I make a proto. Damn, this thing is pretty neat! I bet I could sell a couple of them anyway so it's probably worth putting them out. Which brings me to the next round....
How much should I charge for them? What if that price is too much? What if it is too little? Can I afford to discount them to dealers? What materials should I use? Do I have enough material in stock? If I add another thing to my lineup will I still have time to make everything else? If this thing turns out to be a big seller will I have to drop other items in my lineup just because I don't have time to make all this stuff by myself? Will I lose my mind trying to keep up with it all?
What about all those things people are clamoring for? What about that batch of such and such that I promised to So and So about two months ago. If I make these now I won't have time to get to So and So's stuff. How about Dealers A, B, C, and D? I don't have a clue when I'll get time for them but I really do have to keep them happy.
What about the holidays? It sure would be nice to have some of these for the holidays. But if I make these now what about all the other stuff I was thinking I will need for the holidays? Like whistles and Prybabies® and Bug Out Bars and Imps and Goblins and Micro Bug Out Blades and Micro Cards and Boogers and all those titanium versions of items?
Damn it! They're too cool. I HAVE to make some.
So you see, that's what I'm up against everytime I think about the next item. Will it be worth it? I sure hope so. What will that next thing be? Well, you'll just have to wait to see for yourself. :)
