Those all sound like some form of fear to me. 1 sounds like fear of incompetence: You don't know how to solve the problem, but that's just because "you aren't really thinking about it", so you protect yourself from the idea that you might actually be clueless. #2 happens to me a lot, and it's being afraid that resting/sleeping will prevent you from getting work done (which may be true, but if a nap is going to make things late, it's already too late)
No, it's not a fear of incompetence. It's seriously just a problem of working out what exactly I want to do.
Good case in point from this week: "Write a book chapter on d3 layouts".
Now that's a very vague task and it takes some thinking to even get started on it. You have to even decide what the first step towards a solution is and once you do have it, you then have to do the creative part of figuring out how to write about it.
Creative tasks in particular do not resolve themselves with a focused step-by-step approach, you must solve them by procrastinating (ie. slowly thinking about them freely).
