practice makes perfect

How did the fallacy of (practiced) discipline arise? Has the (not necessary, but certainly enabling) development of histories and establishments around forms like writing, and painting, which lend themselves to effort and dedication (and so, of course, those individuals who can afford such luxuries) an underpinning in class privilege? Feel free to ignore the strained second half of the argument, if you'd like, I know it's even weaker than the first.
