It seems to take more courage to stop doing something than to start something new.
The easier decision is to add more things to the pile. Because you do not want to subtract. What if that thing you subtract is actually the next Facebook?
Reducing big rocks does NOT mean you are going to sit around twiddling thumbs, although there's nothing inherently wrong with that. It simply means you will dedicate more time to spend on the remaining big rocks.
Subtraction is a superpower.
Expect anything worthwhile to take a long time.
