Financial pressure turns small purchases into conscious trade-offs, costing precious mental space.

We often respond to scarcity by demanding more self-control, making the situation even more taxing.

This is when most daily spending is friction-free and automatic. You buy a coffee, simply tap your phone; no worries about where the next latte comes from. The purchase consumes none of your working memory.

When slack evaporates, however, these automatic, harmless habits are instantly transformed into conscious trade-offs. Suddenly, buying a coffee is an active decision: If I spend five dollars here, what am I going to give up later this week?
