"The amount of work your work and life wants of you will always and forever exceed the amount you can do.
You cannot fight this.
It is also a gift.
Once you accept (or re-accept) that there is too much, it becomes easier to turn some things away. You may still feel grief or loss at the things you cannot do. You may feel guilt, especially if an institution or person benefits from you feeling that way. But accepting that you must leave some things undone shifts the problem from one of being not enough to one of being in a position to make choices. And even when those choices are coupled to difficult or prickly constraints, they are still choices."
