Why is it that work becomes so boring after a while? Why projects remains exciting, no matter how exhausting and demanding? Why is the thrill of a deadline better than the monotonous drone of the routine meeting and the impossible boring coworker?
It is all about you brain cells and their connections. Whenever you (or your activities) create new pathways, life is better, explosive, immersive, brilliant.
Repetitious tasks are death, though, and not only figuratively: they mean that little by little your pathways reduce, and your options disappear, and one day you wake up transformed into a cockroach, afraid of light and with an apple embedded on your body. That’s why meetings are emetic, and projects are exciting, even after the 16 hour a day crunches and the impossible goals: those mean growth.
Painting, as Paul Graham suggests, may have worked for 20th century dictators, but now we need more, a certain definite brain workout, and one that pay s the bills and nourish the soul, one that provides excitement and gold, one that goes along with expansion and learning of new disciplines. We need work for intelligent humans that need to learn.
