When I say a certain environment, I mean wild nature. The jungle and the mountains are more similar than the modern city. I suggest our biological adaptation cannot keep up with the rate of man-made change. The Internet dominates our lives now for example. But it did not exist 50 years ago. It took less than one generation. Biological adaptation needs many generations. The unconscious is made up of deep layers. It took millions of years to adapt to the wild environment.

When I say you cannot win, I mean daily habits. We achieve great things (like space travel) with our conscious knowledge: science accumulated over generations. But then at a daily level we do a lot of things which are self-harmful. These come from unconscious choices for survival that have the opposite effect today. Like exercise. Some people do extreme feats. Most struggle to do any exercise. What's the difference? The ones doing it a lot have a deep habit of exercise and adjusted their model of the world. Most who don't want to do it, are driven by the unconscious model that any energy conservation is advantageous.

You have lots of control. My argument is that willpower is not a brute force. You cannot force yourself to change. It only works for a short time. Rather that the key is to adjust your unconscious model and the environment so you change.
