Top things that I learned about here and adopted into my life: There are these new things called "LED flashlights" that make pocket carry of a bright light possible Corollary: Pocket carry of a small bright flashlight makes life much more convenient, so I always have one on me now. The existence and utility of small multi-tools. I now carry a Leatherman Squirt in my pocket every day. Formerly I viewed multi-tools as something you put on your belt only when you needed to do some handyman work, normally left in your tool bag. That carrying a small pocket knife daily is useful. I never carried a pocket knife for years. Now I always like to have a relatively small slip-joint for mundane cutting tasks Corollary: I acquired some decent sharpening tools and have learned how to sharpen much better now. That as an average US urban car-commuting office worker, about 70% of the threads here, while interesting, have no bearing on my life. That there are far more brands of bourbon than I ever knew about, and that I actually like drinking some of them which I would never have tried were it not for the "what is your favorite bourbon" thread.
