Actually, It was harder for me to move from a weekly pay to a monthly one, and even now with all the investing/saving and bill pay automatized via direct debit and standing orders, sometimes I do go over the budget with the food and clothes money. And I just use a crypto card to get over the wage date with a little bump.
I learned about it the hard way, reading about the FIRE movement and MrMoneyMustache and JCollins blogs. We did not have a lot of info back then, maybe just some books from library. If you want to learn about finances, you will learn. I make it into little games and quests with my underage nephews.
Now it is so much easier, with a basic income, you can literally achieve financial independence by the age of 30-40 instead of retirement at 67. If you start saving and planning by the time you are 18. No excuses. But, you may also need to really work hard for it, and delay some rewards and holidays for later.
