#Opportunity Cost

Every Purchase Costs the Time You Live

Finally, Mujica’s message need not lead to guilt or austerity for its own sake. The point is not to stop buying, but to buy consciously—choosing what genuinely supports your life rather than what merely fills it. Some purchases return time (a reliable bicycle, a good mattress), while others quietly demand more time (status-driven upgrades that require ongoing earning).

When you remember that every receipt is also a time receipt, your priorities tend to clarify on their own. [...]

Why Saying No Fuels Real Success

Underneath the simple word “no” sits a core economic idea Buffett often emphasizes: opportunity cost. Every “yes” purchases one outcome by spending time that can never be recovered, and it does so at the expense of other possibilities—even ones you haven’t discovered yet.

Consequently, saying “no” becomes less about rejecting people and more about refusing expensive trades that don’t fit the strategy. [...]

Measuring Cost by Life Spent Living

This idea fits naturally with Thoreau’s experiment in deliberate living. In *Walden* (1854), he details how reducing possessions and needs can expand one’s freedom, because fewer needs require fewer hours sold. The point is not poverty as virtue, but “enough” as a form of wealth—enough to meet genuine needs without surrendering the best parts of one’s days. Seen this way, simplicity becomes a practical strategy rather than an aesthetic. By lowering the “life-cost” of living, a person can reclaim time for reading, walking, friendship, craft, or quiet—activities that don’t just fill life, but constitute it. [...]
