If you understand the independent worker, the self-employed professional, the freelancer, the e-lancer, the temp, you understand how work and business in the U.S. operate today.

But in the end, mastery involves working and working and showing little improvement, perhaps with a few moments of flow pulling you along, then making a little progress, and then working and working on that new, slightly higher plateau again. It's grueling, to be sure. But that's not the problem; that's the solution.

The last few decades have belonged to a certain kind of person with a certain kind of mind-computer programmers who could crank code, lawyers who could craft contracts, MBAs who could crunch numbers. But the keys to the kingdom are changing hands.The future belongs to a very different kind of person with a very different kind of mind-creators and empathizers, pattern recognizers and meaning makers.These people-artists, inventors, designers, storytellers, caregivers, consolers, big picture thinkers-will now reap society's richest rewards and share its greatest joys.

The problem with making an extrinsic reward the only destination that matters is that some people will choose the quickest route there, even if it means taking the low road. Indeed, most of the scandals and misbehavior that have seemed endemic to modern life involve shortcuts.

When the reward is the activity itself--deepening learning, delighting customers, doing one's best--there are no shortcuts.

I happen to be extremely left-brained; my instinct is to draw a chart rather than a picture. I'm trying to get my right-brain muscles into shape. I actually think this shift toward right-brain abilities has the potential to make us both better off and better in a deeper sense.

What's important now are the characteristics of the brain's right hemisphere: artistry, empathy, inventiveness, big-picture thinking. These skills have become first among equals in a whole range of business fields.
