So, technically, it’s irrational to feel troubled by an overwhelming to-do list. You’ll do what you can, you won’t do what you can’t, and the tyrannical inner voice insisting that you must do everything is simply mistaken.

We would be forced to acknowledge that there are hard choices to be made: which balls to let drop, which people to disappoint, which cherished ambitions to abandon, which roles to fail at.
