It’s important to realize that on the journey to achieving big, you get bigger. Big requires growth, and by the time you arrive, you’re big too! What seemed an insurmountable mountain from a distance is just a small hill when you arrive—at least in proportion to the person you've become. Your thinking, your skills, your relationships, your sense of what is possible and what it takes all grow on the journey to big. As you experience big, you become big.
Lacking a clear formula for making decisions, we get reactive and fall back on familiar, comfortable ways to decide what to do. Pinballing through our day like a confused character in a B-horror movie, we end up running up the stairs instead of out the front door. The best decision gets traded for any decision.
The brain makes up l/50th of our body mass but consumes a staggering 1/5th of the calories we burn for energy. If your brain were a car, in terms of gas mileage, it’d be a Hummer. Most of our conscious activity is happening in our prefrontal cortex, the part of our brain responsible for focus, handling short-term memory, solving problems, and moderating impulse control. It’s at the heart of what makes us human and the center for our executive control and willpower. The “last in, first out” theory is very much at work inside our head. The most recent parts of our brain to develop are the first to suffer if there is a shortage of resources. Older, more developed areas of the brain, such as those that regulate breathing and our nervous responses, get first helpings from our blood stream and are virtually unaffected if we decide to skip a meal. The prefrontal cortex, on the other hand, feels the impact. Unfortunately, being relatively young in terms of human development, it’s the runt of the litter come feeding time.
