I enjoyed your article.
Just as an aside, regarding: "Fretting over pennies probably seems foolish to you. Similarly, to those who are capable of generating massive value (and being paid accordingly), fretting over $10K is equally foolish. People who can spend $10K on a hotel room know that $10K is not a lot of money."
--- The extraordinarly wealthy individuals I work with squeeze nickels till the buffalo bellows. I didn't really know what penny pinching was until I saw how cautious these folks are with even very small amounts of money. Although they are generating what seem to me to be exhorbitant incomes, I carelessly throw my money away compared to my bosses.
