It's _all_ drills.
You hardly ever get to swim whole stroke (when you are starting out).
The premise is that your whole stroke is wrong. So you have to deconstruct it. Then work on getting the "micro components" of the stroke right. Then, and only then, re-construct your whole stroke out of the newly learned micro components. (That is my terminology and interpretation, not a TI one).
TI should suit you as it is very Zen and all about Flow and stuff.
