How do you go about changing your life? Do you do it overnight?

The answer, hopefully, is obviously a resounding "no!"

Changing even a single aspect of your life takes time, dedication, and effort. Humans are creatures of habit, and once those habits have become deeply ingrained into our psyche. This is a physical phenomenon that can actually be witnessed within the brain. We'll get to that later in this book.

And yet despite many of us knowing all this intuitively, we still seem to think that we can make huge changes to our lives on a

whim. If you've ever told yourself that you are going to "start a new training program tomorrow" that involves going to the gym four times a week and eating half your current caloric intake... well then you're guilty.
