My dad set me up with a bank account before I turned 10 and us kids were forced to save half of anything we earned once we started our first part-time jobs.
We also tithed 10% of anything we got, which instilled in us an attitude of generosity and the knowledge that our wealth (however small) is a blessing.
My dad also taught us to "never owe anybody anything", except of course, a mortgage. He always demonstrated paying off loans and credit cards within a month (like when our fridge died suddenly and we didn't have the money to replace it same-day). Interestingly, my younger siblings didn't learn this lesson...

My dad was very tight with his money, and as a result, all us kids grew up with a "poverty mentality", when in actual fact, we had everything we needed to survive and we had a great childhood.
It was only when I got married that I realized my "poverty mentality" was actually a hinderance, and there are definite cases where money is there to be spent because we worked hard for it and sometimes we deserve a bit of fun.

So that's my little bit :)
Hopefully someone finds it interesting.
