The word "willpower" is a near-useless metric in a vacuum. It's not the same as physical strength, where its measurement, attainment, and abilities are all pretty straightforward. The mental portion of one's ability to do hard things is a complex function of a ton of variables, both environmental and intrinsic. The portion that is under our control is just one of those variables - though it is certainly a critical portion, and people should absolutely be encouraged to be proactive and try to go above and beyond what they feel like that portion makes them capable of. But to boil it down to "health and wealth are both highly correlated with personal will power... I really have no trouble doing it" is kind of short on substance.
