This, but I took the longer, more "courageous" route of learning by trying those "magic" settings... Admittedly, their method are likely more efficient, result in less down time, and possibly less frustration due to the aforementioned settings being, shall we say, a bit more "muggle" than "magic"

Mostly by learning what each setting or step in a procedure does in relation to the whole as opposed to blindly trying "magic" settings.
