I was one of those people.
Excellent tech income; zero savings other than a 401(k) I barely contributed into.
After an amazing meal at a burger place several years ago, I asked my wife about upgrading to a Model S. She figuratively sat me down (after we literally sat into the seats of our Model 3) and was more straight-forward with me than she had ever been prior to that moment.
"How much do we have saved? Oh, _we_ have basically nothing? Yeah, so I'm not saying no, but you need to fix that before we discuss this again."
I took it defensively in the moment, but not for long because I knew she was right. Building that nest egg became priority #1 since that talk.
That was in 2023. I saved a lot since then. It felt VERY VERY GOOD to look at my savings and say "You know, I could fuck right off for six months if I wanted to. I won't, but I could!" It completely changed my priorities at work.
Now, I've had to drain my savings twice now: once to secure a down payment for our house, and again for a major repair of said home (b/c I am strongly against treating our home as a credit card). Regardless, I chip away a good amount into several savings accounts every two weeks and am expecting to regrow the account within the next year. I can't wait to feel that feeling again!
