"It’s an energy field created by all living things. It surrounds us and penetrates us; it binds the galaxy together."
As long as it does not contradict this line it can be used any way you (the writers) see fit.
The closer it feels to this original line however the better it will sit especially to us
older children.
I feel the most practical way to view how much it controls v user control is the aforementioned symbiotic relationship laced with the kind of recognition we give to raw talent, I shall expand...
I have a skin too few, I am too sensitive, this flaw makes me quiet. Because I am quiet I observe. This quiet observation makes me appear talented at things I have interests in. It
appears as raw talent but I simply know what
not to bother trying to do. I lay somewhere between the next two extreme examples.
Some simply
do have raw talent without much observation, singing for instance, balance for instance, (I could go on forever with this bit) this can be seen as genius
but this is very unstable. Often they just feel gifted and feel they have less control and credit the Muse/Force/Universe.
Now some don't observe quietly or have unobserved talent and do wish they had certain specific talents, They need much more discipline and education but can still reach the same levels and they use technique as a step by step and therefore can control more thoroughly when successful.
Now put the word Force in front of the word talent in the above three examples if you get me.
Then also add the these three examples have an infinite number of degrees between each other and you can basically go back to defining it any way the writers see fit
It's practical use is like a talent/gift at one extreme end of the scale (Vader) and a technique to perfect with cautious study at the other (Kenobi), just like in real life
