Yeah, we learned really early on. I remember I was about...6, maybe 7, I wanted a doll SO! BADLY! and it was more than my allowance for 3 weeks. My parents refused to buy it for me, so I had to do extra chores to earn the money to get it. By the time that I did, I was so pleased with the amount of money that I had stashed up that I didn't want to spend it all on the doll anymore. We didn't have the fake checking account when I was that young, but we were taught right from the start about the value of money. I know exactly the difference between a "want" and a "need" now.
The downside to that is that any extra money I do get, I hoard it because I don't want to spend it. It takes a LOT for me to spend money on myself besides bills, and my bills are very, very few. I literally have shelter, electric, my internet (which is now a necessity), a pay as you go phone (not even a smartphone), and food for me and pets. Oh and my car insurance, too...and I bought the car before I ever "worked from home" so it's already paid off. I have no other bills. (Well, now I'm trying to help sis but that's a different story.) I get told all the time by people who know me that I "need" to "gift" myself something sometimes...so sometimes I spend a little over a dollar on Humble Bundle.
Yeah, don't give away everything.
