My younger brother (homeless and mentally ill) believes that he has all of these wonderful ideas which will make millions.
A few aren’t bad. However, most are what you would expect coming from someone eating out of soup kitchens.
For decades people have been trying to tell him that most ideas from outsiders are worthless. Do you really think that the product managers at McDonald’s haven’t discussed a mini sized Big Mac every product meeting for the last 20 years?
At my previous company, I actually did get a couple of products created, but that was because they were adaptations needed for the Japanese market or products similar to the Japanese competition.
