While akrasia is still an enormous problem for me (as it always has been), it is oh-so-slowly becoming less of one. I have always been a fairly devil-may-care person regarding responsibilities and schoolwork, possibly due to early encouragement about being "smart" and "talented", which led me to think that I didn't HAVE to work hard -an idea that was unfortunately born out in many ways by the evidence throughout my adolescence. I had the impression that I had some kind of supernatural power of avoiding consequences, that I was in some way vastly better and more intelligent than my peers, and so on. This in spite of being an avowed materialist and agnostic; my beliefs weren't propagating properly. LessWrong opened my eyes: The world is allowed to kill me, my innate talents are not enough to get through life (I have to work hard!), and there are right and wrong decisions based on the evidence. Since then (it's been about a year) I've been trying to turn myself into the kind of person who Gets Shit Done. I still haven't finished the Sequences (I'm apparently too akratic even to sit down and plow through something I enjoy reading), so I'm sure there's a great deal more for me to learn... But if nothing else, x-rationality has given me the clarity to know what needs to be done.

Robin and Eliezer ask about the ways to test rationality skills, for each of the many important purposes such testing might have. Depending on what's possible, you may want to test yourself to learn how well you are doing at your studies, at least to some extent check the sanity of the teaching that you follow, estimate the effectiveness of specific techniques, or even force a rationality test on a person whose position depends on the outcome.
Verification procedures have various weaknesses, making them admissible for one purpose and not for another. But however rigorous the verification methods are, one must first find the specific properties to test for. These properties or skills may come naturally with the art, or they may be cultivated specifically for the testing, in which case they need to be good signals, hard to demonstrate without also becoming more rational.
So, my question is this - what have you become reliably stronger at, after you walked the path of an aspiring rationalist for considerable time? Maybe you have noticeably improved at something, or maybe you haven't learned a certain skill yet, but you are reasonably sure that because of your study of rationality you'll be able to do that considerably better than other people.
This is a significantly different question from the ones Eliezer and Robin ask. Some of the skills you obtained may be virtually unverifiable, some of them may be easy to fake, some of them may be easy to learn without becoming sufficiently rational, and some of them may be standard in other disciplines. But I think it's useful to step back, and write a list of skills before selecting ones more suitable for the testing.
