Thanks for mentioning this. Many posts in the sequences I've read so far, especially those concerning biases, seemed interesting, but not necessarily useful: I don't really see how to apply that knowledge to my own life. And when debiasing techniques are suggested, they often sound prohibitively expensive in terms of willpower. That said, I've also read quite a few posts of whose eventual usefulness I am reasonably confident. Off the top of my head, the sequence Joy in the Merely Real seemed really beneficial to me - if only because it gave me a strong argument to read more textbooks.
