I went from being dead set on physics to a joined major of math and physics, following up with a master in math in a while, and instead of thinking "I should learn programming some time", I am currently sitting at a lecture in Python. Had I not encountered lesswrong, I would have been a quirky, regular physicist who lives their life, thinking of some Big Questions, but not actually coming to an answer. I would also not have become atheist quite as quickly. I intend to keep being less wrong in the future, and I've seen results - positive, as well as negative due to what some people consider too much honesty. But all in all, I have improved my odds of reaching my goals.
