Should you keep reading / watching / listening to this thing?

Are you enjoying it? Yes.

Is there some extrinsic reason to consume it (e.g., education, you need the information to complete some other task, etc.)? Yes, unless there's some better way to achieve the same goal.

Did you just barely start it? Maybe give it a little longer.

Are you almost finished? What the heck, cross the finish line.

Otherwise? YEET!
