If you're reading my blog for whatever reason, you're likely a software developer or other well paid technical professional and this will likely apply to you.
When I was broke in college, and first starting out in my career, I wanted to save as much as possible. I applied my analytical mindset to every purchase I made: groceries, gas, clothes. It was exhausting and incredibly time consuming. I was willing to sacrifice my time to save a few bucks.
Now, my earning potential is higher. I'd rather buy back my time and use it to actually build things. Money is a pool of water; as long as the faucet pours faster than the drain, you're fine.
If you still do a cost-benefit analysis on every small purchase, try paying for convenience for one month. Buy the pre-chopped vegetables. Eat takeout. Take the direct flight. See how much time you get back, and put that energy into your career or a side project.
Everything wants your attention right now. Apps, ads, podcasts, news. They're competing for your time because it's valuable. Treat it that way. You probably minmaxed your whole life to get where you are today so don't stop optimizing now. Your time is worth more than your hourly rate.
(I know I sound like a sigma-male, cigar-smoking, 5AM club grindset guy now, but that's' not what I want you to take away. Your time is the most finite resource you have, spend it wisely.)
