I couldn’t agree with these recommendations more strongly if I’d made them myself:
First, you need to read good books. To get the most out of those books, you need to talk about them with other people who are also trying to work their way through them. In addition, you need to write about them in a disciplined and focused way. Both of these tasks require supervision and guidance by more experienced learners—preferably those who have already gone through an educational program that takes both discussion and written analysis to the highest level.
You owe it to yourself to read the whole thing.
