In the article “The Making of an Expert”, the author also makes the case that deliberate practice involves two kinds of learning:
“[…] improving the skills you already have and extending the reach and range of your skills. The enormous concentration required to undertake these twin tasks limits the amount of time you can spend doing them.”
These are useful distinctions for the 2Time user.
The author makes the points that
“[…] musicians over 60 years old who continue deliberate practice for about ten hours a week can match the speed and technical skills of 20-year-old expert musicians when tested on their ability to play a piece of unfamiliar music.”
Again, this is good advice for the executive who refuses, for example, to use a PDA of any kind and is forced to lower levels of productivity.
