Some days of collapse are the culmination of many small not-no's.
To not say no, is a not-no. And with the not-no, you forge ahead into indecision, uncertainty, and taking care of others. Not, yourself.
The not-no's will always catch up as a wave of fatigue, a burst of irrational frustration, a need to disconnect from everyone. On one day, it all crashes as the many small not-no's pile on.
Never do because of a not-no.
Never accept a not-no.
Only take a heck yes. Only do when you can say heck yes.
Relating, is not work.
