Hours spent in serious study of the game was not just the most important factor in predicting chess skill, it dominated the other factors. The researchers discovered that the players who became grand masters spent five times more hours dedicated to serious study than those who plateaued at an intermediate level. The grand masters, on average, dedicated around 5,000 hours out of their 10,000 to serious study. The intermediate players, by contrast, dedicated only around 1,000 to this activity.

Next time you hear that an apparently perfect marriage between two perfectly well-matched partners is on the rocks, don't be too surprised. It's a clear case of set-up overestima-tion. Frankly, anyone who's spent more than five minutes in a relationship should already know that without ongoing fine-tuning and repairs, it doesn't work. All partnerships have to be consistently nurtured. The most common misunderstanding I encounter is that the good life is a stable state or condi-tion. Wrong. The good life is only achieved through constant readjustment.
