One of my favorite websites to browse is www.lifehacker.com. Today, they had this wonderful article here about deliberate practice. It mentions Mozart, but focuses much on basketball player Kobe Bryant. Parents and other guardians have frequently complained about lack of progress from their child even though they are "practicing". What's likely going on is that they're sitting down at their instrument, but are they really doing proactive deliberate practice with a goal in mind? This article explains very well. I encourage everyone to read it.
