You will never be able to give others enough of your time/energy/attention—they’ll always gladly demand and accept more.
This is where prioritizing others over yourself crashes and burns.
There will never be “left over” time/energy/attention. “Extra” is an illusion. The demands of others is a bottomless pit.
Pay yourself in time/energy/attention FIRST. Then, when full, give extra or what you have left over to others.
