I agree, because I am facing the same problem everyday. I cannot manage a simple budget that's why every time I got a salary I will let my uncle to manage the portion of my salary and he will budget it for the whole month. I am having a hard time always to breakdown my expenses so I decided to track it in notion for me to help myself and be more organized than before.
Why not push yourself to learn finance management? It always pays well if we invest in ourselves. It may take time to accustom ourselves to financial management but once learn, you do not need any third party to manage your money for you. Since not all the time you are with your uncle, one way or another you have to part ways especially when you have your own family. So it is better to learn how to manage finance now and you can even get your uncle's insights and advice as you learn to manage your own money.
I agree with the advice given by serjent05. Because in the end we are the ones who have to manage our own finances. Because sometimes we shouldn't always bother other people. Even if it's our own uncle. So starting to broaden your horizons by learning about economics starting from financial management is something worth trying. I believe you (molsewid) can do it. Because I also have an acquaintance who initially had difficulty managing finances. In fact, he even studied economics. But he lacks discipline in financial management. But he kept trying and trying to manage his own finances and well now he is much more reliable. Sometimes the inability to manage finances does not come from a lack of insight. Sometimes this can also arise due to lack of discipline in our own lives. And lack of discipline arises due to an inability to control our emotions. So my advice is to also study economic psychology and emotional management. Because sometimes managing finances is almost like managing in trading.
