We get good at doing things. we like it. We are in the zone. we cruise.Then we hit a plateau. No more improvement, no acceleration in performance. We shouldn't let that happen. We need to be shaken up once in a while. The bar has to be set higher. We need to make better/become better at, the things that really matter...
That is what Ray Bradbury says beautifully in his Fahrenheit 451.
"We need not be let alone. We need to be really bothered once in awhile. How long has it been since you were really bothered? About something important, about something real?"
When were you really bothered last?
