You are THE expert at saying “yes”.
Sometimes enthusiastically, even as you’re wondering why you’re over-booking, over-promising, over-extending yourself yet again.
But then you remember the feeling you get when you say “no”. The dread. The sinking feeling. The feeling that you’re being a withholding jerk.
Wrestling with your feelings to say “no” is infinitely harder emotionally than caving and just saying “yes”. Except saying “yes” is fatiguing. So tiring. And leaves too little time for you to do the things you’d like to do for yourself.
