The human mind designed to look for ways to be more efificient thus saving energy. We do that by creating habits. Either those habits are serving you = creating more energy and or saving energy or forming bad habits = draining our energy
If we are focusing on the wrong things, mindless things, things that are out of our control we are draining our energy without even knowing subconsciously. Then we ask ourselves why the fuck am I soo tired.
We GET what we focus on
