Meaningless platitude. All the things mentioned (visualisation, scheduling, breaking into smaller tasks, etc.) are proven to work. If you cannot do a task but you do the above things, you will eventually be able to do the task. You know what isn't proven to work? Willing your brain to "just do it" like this article implies.

Agreed. But there’s still a type of Zeno’s paradox if you don’t start and continue and finish the thing. As someone that has no trouble planning or starting but a lot of trouble continuing to the end, I find this kind of stuff helpful to completing what I set out to do.

As Jobs said “real artists ship.”
