Recent research has highlighted two purchases that reliably boost happiness more than buying material items: spending on others and buying back time. Studies show that directing money towards other people can yield a bigger emotional return than spending on ourselves, as it strengthens social ties and creates lasting connections. Additionally, paying to save time by outsourcing chores or eliminating hassles has been proven to increase overall well-being, especially for individuals feeling time-stressed.

Experiences also tend to bring more long-lasting satisfaction than material goods, and prepaying for these experiences can heighten enjoyment by lowering "payment pain" and extending anticipation. By incorporating both prosocial spending and buying back time into everyday choices, individuals can shape happier days and improve overall well-being. Ultimately, the research suggests that how we spend our money can significantly impact our happiness, with generosity and time-saving purchases proving to be the most effective in increasing joy.
