Luckily I'm not interested in any of the above, but I'm genuinely curious as to how this is even possible without sacrificing something big. During your waking hours, you have to work, commute to work, cook or buy food, wash dishes, take a shower, do the laundry, mow the lawn, shop for personal care products, make sure your vehicles are maintained, etc. I don't have much spare time, and the spare time I do have is spent on running, vacations, and various non-running activities like snowboarding or taking a few minutes to look through letsrun.
How do you guys do it, and is it even worth the effort?
