This is an interesting article. I believe that anyone interested in note-taking will benefit from reading it. This endorsement does not mean, of course, that I would agree with everything said in it. But I do like the distinction between learning and training: "learning to learn depends on a certain style of thinking . An important distinction here is between education and training: education is learning what you should do and when and why to do it, whereas training is learning how to do it. Obviously, to succeed you need to be both educated and trained." Universities used to be "into" education, but now are in the process of veering entirely into training.
I am not so sure about rule 6 that emphasizes concentrating on the successes of others: "'As Hamming says, because “there are so many ways of being wrong and so few of being right, studying successes is more efficient, and furthermore, when your turn comes you will know how to succeed rather than how to fail.' In addition, he notes that 'vicarious learning from the experiences of others saves making errors yourself.'" This may well be true in science, but it is certainly not true in other subjects. It's not a bad idea to eliminate some of the many ways of being wrong. I wish I had!
1. I know that this is an over-simplification or a bit of a caricature. But caricatures are important precisely because they exaggerate some features at the expense of others in order to make some(one) or something more recognisable.
2. I have referred to Richard Hamming before before.
