I took Yale's 'most popular class ever'—and it completely changed how I spend my money

"Money doesn't buy happiness." For most of my life, I've found this idea impossible to justify. Anyone who says a million dollars won't make them happier must be delusional.

Money gives you more control over your life; the freedom to retire early, the security to support yourself and your family, the comfort of buying things and experiences that excite you, the option of saying "yes" when your friends invite you to dinner…I could go>Money ≠ happiness. Really?

Santos references several "annoying features of the mind" that influence us to chase after things that don't really make us happy. Many of the materialistic goals we strive for make little to no lasting impact on our overall life satisfaction, Santos argues. One of the the main misconceptions she addresses is money.
