Don't work on an idea just for the money.

Work on something that you will use. Something that you really want to exist and there are only sub-par or no alternatives out there. Whether this is something that will entertain you or fix a problem of yours.

It is most likely that if you find this product of use then someone out there in the world will think the same as well. However, this could be five people or thousands of people, it is hard to predict.

If it is really good then the money will follow, but instead of money, take satisfaction that you have created something from an idea and that there's at least one person other than you that is using it.
