The primary purpose of your brain is to keep you alive. Our brains focus on 3 simple motivations to increase our odds of survival: avoid pain, seek pleasure and conserve energy. This is the motivational triad. You will always be motivated to do something that won’t hurt you, feels good, and is easy. This is how we humans survived back in the day. We were motivated to hunt, have sex and seek warm shelter by our desire for pleasure. We stayed alert to avoid danger. We didn’t go jogging just for the sport of it. We conserved our energy.
Powers of Ten (1977) takes us on an adventure in magnitudes. Starting at a picnic by the lakeside in Chicago, this famous film transports us to the outer edges of the universe. Every ten seconds we view the starting point from ten times farther out until our own galaxy is visible only as a speck of light among many others. Returning to Earth with breathtaking speed, we move inward- into the hand of the sleeping picnicker- with ten times more magnification every ten seconds. Our journey ends inside a proton of a carbon atom within a DNA molecule in a white blood cell.
Angeles set in motion the sphere of fixed stars, which in turn drives all the other spheres. [France, 14th century]
