the most surefire way to health is consistency and the most consistent path is the easiest one. organize your life in such a way that the healthy choices are easier than the unhealthy choices and build habits and rules that do not require much in the way of motivation or conscious effort to follow. i don’t keep junk food in the house for this very reason, it enables me to be a lazy asshole and still make a good choice without exerting any effort at all. cardio is an equally brainless option that is very easy to skinnerbox for yourself. if requires next to no effort to ride a bike and play mmos all day for what are effectively free endurance gains.
