Commit it to paper I suppose, give it permanence and a sense of place.
You consider it, sitting on a bus, watching television, going for a walk, wherever. Conclusions are drawn by a biased mental jury that its fantastic; amazing; revolutionary; the world needs to know! People will be clapping you on the back for years to come, the accolades and kudos will thunder down from on high and you’ll be there to accept them in the gentle, unassuming manner that only the gifted can truly achieve. But its not over -confidence is it? Not when an idea like this beautiful neuron surge is the subject.
And you sit down to gift some paper with the fruits of your subconscious. But the holes, faults and glaring problems become obvious in the harsh light of the real world. In your mind you had been building it up, building it up, adding a wing here, conservatory there, knocking a few walls through, until it resembled some un-fair Hall of Mirrors. And still you plow ahead. But just like a boiler with a faulty rivet, you start losing steam fast. Your idea can stand up under scrutiny, its not ground-breaking, just another attempt to express what you never really could.
Imaginations on the fritz again.
