If insanity is doing the same thing over and over and expecting different results, then sanity would simply be a refusal to repeat broken actions. This book is an explanation of just that, everywhere it counts.
When we fight nature, we suffer. Life is no more complicated than this. Why then, IS life so complicated? Because we don't even recognize human nature, uninterrupted. We can't follow what we don't see, but the laws of human nature point to the truth, no matter how obscure our view is. We need only look, with the laws in focus.
We need only love, and to get out of our own way.
