Not Today Satan
Your mental state and physical self are linked. So, you can’t improve one without the other.
Bottom line up front, stress kills gains, so today is just an assignment to cut some out.
Make a list of everything you have to do this week.
Once you do that, you are going to delay, defer, or never do (preferrable) 10% of these things. While I recommend prioritizing these, you do you.
Bonus points if you tell the person “Not Today Satan”.
