" In my recent WSJ article on age and creativity, I didn't have space to discuss the fascinating research of David Galenson, an economist at the University of Chicago who brings together a vast array of evidence to better understand the nature of creative production over time. Galenson divides creators into two distinct categories: conceptual innovators and experimental innovators. In general, conceptual innovators make sudden and radical breakthroughs by formulating new ideas, often at an early age. In contrast, experimental innovators work by trial and error, and typically require decades of tinkering before they produce a major work. For an excellent summary of Galenson's work, check out this Gladwell article. "
Decades of tinkering: should be ok with that and not lose heart over the fact that slow plodding produces can also result in magnificence.
