The advice works, but only if you have the strength to do it and not everyone does.
Realize that some of these aren’t just decisions you have to get right every day (like walking every day), they’re decisions you have to get right 86400 times a day. If you crave junk food, you don’t just decide “I’ll stop eating it”, you have to make that decision every second of every day, because if you slip once, you’re fucked.
