One of my pet theories is that 95% of business books are just one good idea expanded into 300 pages. The book, The Art of Learning, is just the opposite. Josh Waitzman (the kid who was featured in Searching for Bobby Fischer) packs the book full of insight that I had to set it down every few pages.
One of Josh's points is talking about the two types of intellingence theories adopted by each of us:
Early on as a parent, I mistakenly thought encouraging my kids was delivering Entity feedback. I'd say, "You're smart. You got this!" That was just not right. Since then, I've tried to push my kids to understand the Incremental approach to intelligence. You gotta work hard and make some mistakes to get great at anything.
