Modifying your environment so that you can completely avoid the need to use willpower is ridiculously useful.
My personal example: arranging to go exercise on the way to or from somewhere else will drastically increase the probability that I’ll actually go. There’s a pool a 5 minute bike ride from my house, which is also on the way home from most of the places I would be biking from. Even though the extra 10 minutes round trip is pretty negligable (and counts as exercise itself), I’m probably 2x as likely to go if I have my swim stuff with me and stop off on the way home. The effect is even more drastic for my taekwondo class: it’s a 45 minute bike ride from home and about a 15 minute bike ride from the campus where I have most of my classes. Even if I finish class at 3:30 pm and taekwondo is at 7 pm, it still makes more sense for me to stay on campus for the interim–if I do, there’s nearly 100% likelihood that I’ll make it to taekwondo, but if I go home and get comfy, that drops to less than 50%.
