I think in a lot of cases manual labor is extremely ironed out because the workflow is defined before the work is done. - Pick up shovel - Move dirt from pile A to pile B There's not much else to think about, you do it and you know you're doing the right thing so there's no opportunities to second guess yourself into not doing it. Compare that to a vague action of "build xyz app". There's a million things to think about and you can easily talk yourself out of it because maybe you're doing what you think is the wrong thing (note: the "what you think" is a really important phrase here). But if you break that down to "open up code editor" and "design user registration page" that at least starts to get less vague. Eventually you get into precise actionable tasks like "create user model with an email, password and username" which you can start progressing on without much distraction.
