What’s your idea?
Does your idea solve a problem?
Quantity of ideas does matter when we practice generating ideas. But, when we apply the ideas to the real world, quality of ideas does matter.
Not a few people miss the point. Some people tend to focus on the uniqueness or originality of the idea rather than its effectiveness. Some people focus only on the effectiveness. Only the small number of people are good at generating and incubating ideas from both points of view: uniqueness and effectiveness.
Any ideas can be improved. Even the ones that are not unique or original. Even the ones that would not solve a problem at this moment. We just need to identify which one is missing — uniqueness and effectiveness — and work on that. If your ideas miss both, give yourself another try.
