I try to do this, but it often times derails into irrelevant (to the initial goal) tasks like "okay, let's Format this excel to look as pretty as possible", "now convert every expression into properly typed latex" and things like that. They might seem somewhat related or sometimes even productive, but result in me taking a long time to do something.
Any ideas how to keep these sub goals in direct service of the main goal?
