The piece introduces the concept of "vanity activities," which are pursuits that seem beneficial or virtuous but often provide little real value for the time and effort invested. The author starts with credit card churning as a prime example, where individuals chase rewards like airline points or cashback, only to find that the time spent may not justify the financial gain. One insightful comment posed the question of whether such activities are more about hobbyist enjoyment than practical benefit. The author expands this idea to several other activities that fall into the vanity category. Reading the news, for instance, often feels necessary for staying informed, but much of it is irrelevant in the long run. Biohacking, while aimed at improving health, can turn into a game for some, focusing more on the enjoyment of tracking blood metrics than actual health benefits. Ethical consumption practices like avoiding plastic straws may feel good, but they don't significantly impact environmental issues. Networking events and productivity optimization, too, are often more about socializing and the satisfaction of checking off tasks than about actual career advancement or effectiveness. The author encourages readers to examine their own activities through this lens. Recognizing something as a vanity activity might lead to a decision to stop it altogether, or it could help clarify one's motivations, allowing for a more honest relationship with those pursuits. This reflection on how we spend our time is positioned as essential, given that our time is a finite resource.
