Activation of "How to Draw anything?"

About a month back, I just photoread a book for recreational purpose. It was on how to draw better. Ever since that I have improved in my drawing. Without actually activating that chapter of figure drawing.

Recently I was a drawing a scenery, purely out of my memory. So I drew the whole thing with the minimal detail, as I recollected. I then compared the drawing with the scenery. Little that I knew, I had put in detail drawing of certain building without my conscious effort in looking for that detail. I was so fixated in drawing other buildings, that I didn't take any effort in knowing the detail of that building.

Well I learned one thing from this activation (this is what I call this). We must not be fixated with single perspective outcome. Just step down, and activate as naturally as possible.
