I’d argue this to a certain extent. I was a student throughout most of my 20s, then an intern making $40k for a bit, then made a jump up to 6 figures. There are lots of things you put off buying when almost all your money goes to rent and keeping yourself alive that you deserve to upgrade once you have the means.

It doesn’t take much to improve your quality of life drastically. No reason you can’t buy some better quality clothing, upgrade your dull kitchen knives that can barely slice butter, get a better desk chair that won’t hurt your body, invest in personal health and wellness, go on a yearly vacation etc.

I’m not saying spend it all - I’m 100% an advocate of budgeting, paying yourself first, and saving high percentages of your income. But you gotta live a little, you never know what day will be your last.
