Assuming that health is the ultimate wealth, and that health is more important than money, then begs the question: can money buy health? And if so, how can you use money to become more healthy?
Some thoughts — money for physical and physiological strengthening. For example, buy a chin-up bar, kettlebells, or use money for a gym membership. Also money on highly nutritious foods — more red fatty meat, steak, beef.
Also the best part of being self employed and having “financial independence”— being able to take a nap whenever you want to during the day, sleeping however early you want (6:30pm, 7:30pm) and waking up however late you want without the agency of an alarm clock.
