Something can be really simple, yet very hard. Like saving money or losing fat and building muscles.

I don't know what that means. Building muscle involves incredibly complicated biological processes, there's nothing "simple" about it. In the parent comment the "simple" advice is also fallacious.

We don't need to know all the intricacies of how something happens behind the scenes. The actual task of how to do to it is very simple.

You keep redefining "simple" to make it work.
