Narrow Beam SBTI type

Calculates living expenses down to the cent but still ends up in the red every month. Knows the exact price of everything at the convenience store. When a friend suggests an expensive restaurant, checks the menu online beforehand and pre-calculates their order. Dreams about being rich. Watches 'how I saved a million' videos. Still buys the expensive coffee.

The 20th of the month. Opens banking app. Stares. Closes it. Opens it again. Stares more. Transfers 50 yuan to the food budget. Orders takeout with a 3-yuan coupon. Spends 20 minutes choosing to save 2 yuan. Still buys a 28 yuan bubble tea to 'treat myself.'

Putting everything into one thing isn't irrational — it's a rule that makes internal sense: limited resources, concentration produces results, spreading thin means everything suffers. So you pick one direction and pour it all there. The 3000-yuan device next to the empty fridge isn't a contradiction. It's a priority system. What's harder to see is that the same logic runs on relationships: one person who gets the real you, one friendship that gets actual investment, one thing holding all the emotional weight. When that one thing breaks, there's no backup. What you call focus is also protection — staying concentrated means you never have to sit with not knowing what you are when you're not aimed at something. Six days of instant noodles aren't sacrifice. They're what happens when you've already decided where everything goes, and your own well-being didn't make the cut that week.
