From a NYT book review of The Genius in All of Us by David Shenk, printed March 21, 2010:
“Whatever you wish to do well, Shenk writes, you must do over and over again in a manner involving, as Ericsson put it, “repeated attempts to reach beyond one’s current level,” which results in “frequent failures.” This is known as “deliberate practice,” and over time it can actually produce changes in the brain, making new heights of achievement possible. Behold our long rumored potential, unleashed at last! Shenk is vague about how, exactly, this happens, but to his credit he doesn’t make it sound easy. “You have to want it, want it so bad you will never give up, so bad that you are ready to sacrifice time, money, seep, friendships, even your reputation,” he writes.”
Sounds like a tprs-er to me.
