Stop talking about your idea.
If you want to take your idea past the idea stage write it down.
And keep it to yourself
Whatever you do, do not (do NOT) kick it around with colleagues – at least not until you understand it fully and you can present it passionately.
Luke Williams, a fellow at Frog, writes in FastCompany.com (The Three Biggest Barriers To Innovation…) that abstraction can kill an idea, but expressing the idea in sensory terms can give it the best chance of success.
How do you express it in sensory terms?
Describe the idea in as much detail as possible.
Describe what it looks like. Better yet, draw a picture.
Describe the emotional impact. (All great ideas have one).
How will we feel if we adopt your idea?
Don’t tell me your idea.
