     The latest research suggests that the key factor separating geniuses from the merely accomplished is

not IQ, a generally bad predictor of success. Instead, it's purposeful practice. Top performers spend

more hours practising their craft. If you wanted to picture how a typical genius might develop, you'd take

a girl who possessed a slightly above average language ability. It wouldn't have to be a big talent, just

enough so that she might gain some sense of distinction. Then you would want her to meet, say, a

novelist, who coincidentally shared some similar qualities. Maybe the writer was from the same town,

had the same family background, or shared the same birthday.

    This contact would give the girl a vision of her future self. It would give her some idea of a fascinating

circle she might someday join. It would also help if one of her parents died when she was 12, giving her

a strong sense of insecurity and fuelling a desperate need for success. Armed with this ambition, she

would read novels and life stories of writers without end. This would give her a primary knowledge of her

field. She'd be able to see new writing in deeper ways and quickly understand its inner workings.

     Then she would practise writing. Her practice would be slow, painstaking and errorfocused. By

practising in this way, she delays the automatizing process. Her mind wants to turn conscious, newly

learned skills into unconscious, automatically performed skills. By practising slowly, by breaking skills

 down into tiny parts and repeating, she forces the brain to internalize a better pattern of performance.

Then she would find an adviser who would provide a constant stream of feedback, viewing her

performance from the outside, correcting the smallest errors, pushing her to take on tougher challenges.

By now she is redoing problems-how do I get characters into a room-dozens and dozens of times. She

is establishing habits of thought she can call upon in order to understand or solve future problems.

    The primary quality our young writer possesses is not some mysterious genius. It's the ability to

develop a purposeful, laborious and boring practice routine. The latest research takes some of the magic

out of great achievement. But it underlines a fact that is often neglected. Public discussion is affected by

genetics and what we're "hardwired" to do. And it's true that genes play a role in our capabilities. But the

brain is also very plastic. We construct ourselves through behaviour.
