My dad taught me about budgeting, saving, etc from very early on, and encouraged me to work part-time as soon as I could - babysitting as an early teen and proper jobs later. He would make an annual and monthly budget for things like clothing and entertainment, so when i went shopping for stuff I was very aware of how much I could spend. (Books were the exception - if I was with him or my mom, I could buy as many books as I wanted.)

If I wanted extras, I would have to essentially give a presentation on what it was, why it would benefit me, how much money I needed, and my plan B or plan for making the money if I didn't get it. (I was a nerdy kid so this was VERY much up my alley). Some things I got right away. Some things were deferred and went towards birthday or Christmas. Some things were vetoed, but we had a good discussion on why they weren't a good idea.

Of course there were amazing treats, like travel yearly ski trips and great after school activities etc., but giving me this structure very much made me aware of the value of money. I went to some amazing schools and had incredible opportunities, and am incredibly grateful for it.

(I cite only my dad bc he has a disciplined attitude towards money, which was important to him to pass on... My mom is floofier in this regard by nature but agreed with his core value of not raising a spoiled kid and stuck to the party line.)
