The Errant Æsthete

This short review of the book This Is Your Brain on Music shares similarities with Stephen Dubner’s post on deliberate practice:

In his review of Your Brain on Music, John Walkenbach says:

many people have found that you can become an expert in anything if you devote a minimum of 10,000 hours to it. Assuming a 40-hour week, you can become an expert at something in about five years. If you’re not working at it full time, figure three hours per day for ten years.

In the Freakonomics post, Dubner says:

excellence is accomplished mainly through the tenets of deliberate practice, which are roughly:
1. Focus on technique as opposed to outcome.
2. Set specific goals.
3. Get good, prompt feedback, and use it.

Moral of all this — get busy! [via link]
