I'm reading The Survival Guide: Home Remodeling by Diane Plesset (Amazon affiliate link). It has nothing remotely to do with magic, in terms of spells and rituals or correspondence charts. But it is an interesting book about home remodeling and how to work with interior designers. And most importantly its teaching me to be keep an open perspective and learn about the world from other angles other than what I'm comfortable with. That's one reason I like to learn different subjects outside of my fields of expertise. The chance to learn something new, consider a different perspective, and even adapt some of that to one's magical practice can be very useful...and in this case reading this book reinforces how important it is to pay attention to the details, ask the right questions and do the necessary groundwork in order to turn your imagination into reality.
So often with magic books the discussion focuses on the metaphysical, but doesn't necessarily emphasize awareness of the mundane details and how much they can make or break the success of a magical work. To me, paying attention to the details involves paying attention to the mundane details as well as the magical details. So you learn about those mundane details and apply them as well as doing the magic. This process makes it easier for magical work to manifest into measurable results, and at the same time teaches the value of doing the work on all levels. The benefit of doing the work on all levels is that not only do you improve as a person, but you also improve as a magician, because you can see all levels as opposed to just focusing on one and trying to put all your effort into that one level. Success of any sort is best achieved by working all the angles instead of just one.
