More than anything, I want you to get this:
Your health is not made on your best days, nor your worst.
Create daily habits, but judge your progress by looking at your week and your month – aim for 80% “supportive of health goals” actions, and then don’t feel guilty when 20% is spent on some perhaps “less than supportive” actions.
Health is a long game. You can’t make it happen in one day, and you can’t ruin it in one day.
