As a child, no one explained to me how to properly deal with the income that came in. That you should not spend it all within a certain period of time. You should put aside some part or, better yet, invest this money.
That is why, it is also a privilege when kids have guardians that are being taught on how to be financially well and be good at managing their finances. And those people that have grown without such but still managed to be good with their finances, you're all legends and you've come a long way for sure and learned a lot of it from your experienes. Also, the kind of old life that you've got is one big factor as to why you have been self taught on how to be financially educated. Because going back to the former life without good finances is what we are trying to avoid.
