This is deceptively difficult but profoundly powerful. The Getting Things Done methodology also talks about natural project planning like this.

But small doesn’t mean “no thought required”. It requires mental power to distill larger projects (or goals) into small steps.

My mistake, for a long time, was thinking that breaking it down into smaller steps was less brainpower.

Better clarity, but also more upfront mental energy to distill what the next physical action to be done was.
