If you're reading this, you're probably a well-paid technical person. This is for you.
Broke in college, I optimized every grocery run and tank of gas. Exhausting. I was trading hours for singles.
I earn more now. I'd rather buy time and spend it building. Money is a pool: as long as the faucet outruns the drain, you're fine.
If you still run a full cost-benefit on every small purchase, try a month of paying for convenience. Pre-chopped veg. Takeout. The direct flight. Put the hours into work or a side project and see how it feels.
Everything is competing for your attention because it's worth something. You already min-maxed your way here — keep treating time like the scarce input it is.
(Yes, this skates close to grindset Twitter. Ignore that part. Finite resource, spend it on purpose.)
