Chuck, I'm not sure that is quite so. Miles wanted to absorb himself into the current jazz scene. I've never read anything that implied that he dropped out of Julliard for anything other than for musical reasons, nor that for that matter, that he made much money in those years by doing so. Such aphorisms look cute enough and roll off the tongue easily enough but are a bit disingenuous. The degrees either have value or they don't, depending on one's goals, how these degrees apply to those goals, and what the individual took away from the processes they went through in obtaining those goals. Devaluing them out of hand as in that glib quote doesn't do anyone any good, especially the OP who's looking for some constructive guidance.
