I agree, if you're trying to hit three different goals at once (improve sleep, workout, and diet) you will end up overwhelmed.
Instead my approach would be to pick one of those things, like "improve sleep" and then design a bunch of changes around that.
These are just examples, but the idea is I go into a change knowing I won't stick to all of these, but if even a handful succeed, I will have made progress towards my goal.
Those who can be patient enough to focus on just one microhabitat at a time definitely can and should take that route. But since that never quite worked for me personally, this is my workaround. 😀
