I half agree with this. I've employed some of the above productivity tricks when I want to get things done really badly. I was productive.

I've also ignored all of these tricks had equal productivity.

When I don't want to do something, eliminating all familiar procrastination tools will just make me create or find new procrastination tools. I think the best advice is that small sentence in your post "you either do it or you don't". Embracing that mentality, I either do something or I put it behind me and do something else.
