Keep it simple and boil it down to the big categories: for example, physical health, mental health, social health. Don't try to do it all at once, if you can touch one category each day great. If you can touch every category every day even better.

The good thing is that most healthy activities feel good to do, so they're self-perpetuating. They don't give the instant shot of dopamine as unhealthy activities but they do give you something. Furthermore, they feed into each other. Doing one habit makes the resistance to starting another less.
