I came up with a good idea, of which i won't tell

But the following probs come with it.
The idea will work but not sure how to make money out of it.
Who to tell, Trust is a big thing .
Money needed to invest in it , so as to get good coveage before others try to do same.
Time to go and get the third parties invovled to make it work.
Been thinking about it for years , but prob won't ever do anything with it.Then it might be a load of rubbish and may not work is the other worry so keep it to myself and don't look a fool :
