After a not-so-very fruitful evening of remembering formulas, I have come to a conclusion that tabloids are more popular than sudoku or chess magazines is that people love stories with a bit of soul or personality. Mechanical knowledge is the most uninteresting thing one can learn. The only good thing about it is the feeling of kicking nature's ass you get when you finally start understanding what you need to do to solve what you need to solve.

For me that's a rather rare feeling. Not worth it.
