"Something as natural as walking consists of repeatedly setting the body off kilter. Each time we shift our weight from one foot to the other we lose our balance for a fraction of a second. We learn to walk by learning to displace ourselves without falling, and recovering our balance almost simultaneously." - Ghost Radio by Leopold Gout.
I don't remember the plot of the book, but the passage haunts me, I think of it often. Found it in my guitar notes, scrawled on a scrap of paper.
