One of the biggest problems in learning is that you don’t know how much you don’t know, and this raises two questions:
- how do you find out that there are huge gaps in your knowledge that need to be filled ?
- how do you know whether or not the material you’re learning from is any good ? (There’s a LOT of garbage on the internet.)
I can across an interesting little post from John Scott (of ApEx fame) a little while ago that shows the effect of the first question very clearly.
