I think there's an investing checklist item to be developed from this article, specifically related to this: "So yes: taking a break is important. But make sure you do something that makes you happy, as positive moods make us even better at diagnosing the value of our creative work. After a few relaxing days of vacation, you’ll suddenly know which new ideas deserve more time and which need to be abandoned."
I’ve always been fascinated by the failures of genius. Consider Bob Dylan. How did the same songwriter who produced Blood on the Tracks and Blonde on Blonde also conclude that Down in the Groove was worthy of release? Or what about Steve Jobs: what did he possibly see in the hockey puck mouse? How could Bono not realize that Spiderman was a disaster? And why have so many of my favorite novelists produced so many middling works?
The inconsistency of genius is a consistent theme of creativity: Even those blessed with ridiculous talent still produce works of startling mediocrity. (The Beatles are the exception that proves the rule, although their subsequent solo careers prove that even Lennon and McCartney were fallible artists.) The larger point is that mere imagination is not enough, for even those with prodigious gifts must still be able to sort their best from their worst, sifting through the clutter to find what’s actually worthwhile.
“Artists have a vested interest in our believing in the flash of revelation, the so-called inspiration…shining down from heavens as a ray of grace. In reality, the imagination of the good artist or thinker produces continuously good, mediocre or bad things, but his judgment, trained and sharpened to a fine point, rejects, selects, connects…All great artists and thinkers are great workers, indefatigable not only in inventing, but also in rejecting, sifting, transforming, ordering.”
