A way to think about it is a programmer: your mind is just a lot of functions - written by the `consciousness()` function, that has the main loop. You have the `moveLeftFootUp()` function, that can be called by the `walk(speed="normal")` function, that can be called by the `morningWalk()` function, etc.

Consciousness is the caller. You/It can consciously manually call `moveLeftFootUp()`, then `moveRightFootDown()`. Or maybe you were calling `walk(speed="normal")` and stepped in and started debugging that function's code at that level, step by step. Also, these functions sometimes raise exceptions, which are either handled by the function's caller automatically or bringing it to the caller's attention (i.e. the `conciousness()` main loop).

Learning to walk involves first manually calling `moveLeftFootUp()` and `moveRighFootDown()` order (once you have drafted those functions) in different order to get right how that should be done, then prototyping some `walk()` function code. The initial version of the `walk()` function at the begining isn't very robust and doesn't handle a lot of edge cases, thus raising exceptions all the time and requiring a lot of conscious effort. Of course, you are also adjusting `moveRighFootDown()` and `moveLeftFootUp()` at the same time or maybe creating `moveFoot(feet,direction)` function, etc.

But in the end, after all the fine adjustments of the code, you basically get the code for `walk()` right, it stops raising exception's to the main loop and doesn't require too much effort. You can just call the `walk()` function and it just works automatically (unless you step in with the debugger) - or you can continue creating new functions that call `walk()` inside those, confidently.
