Discoveries in science and technology are thought by "untaught minds" to come in blinding flashes or as the result of dramatic accidents. Sir Alexander Fleming did not, as legend would have it, look at the mold (霉) on a piece of cheese and get the idea for penicillin there and then. He experimented with antibacterial substances for nine years before he made his discovery. Inventions and innovations almost always come out of laborious trial and error. Innovation is like soccer; even the best players miss the goal and have their shots blocked much more frequently than they score.
The point is that the players who score most are the ones who take most shots at the goal and so it goes with innovation in any field of activity. The prime difference between innovators and others is one of approach. Everybody gets ideas, but innovators work consciously on theirs, and they follow them through until they prove practicable or otherwise. What ordinary people see as fanciful
