I try not to waste my mom's money on me
That sounds nice, why do you feel that you have wasted it before?
I haven't made my own money before, but by working right now, I can make her proud.
It's great that you're earning your own money now and not spending your mom's. It's nice to be mindful and frugal with your parents money and financial support.
Me too, I'm pretty good at managing money.
I am really proud of you! It can be really hard for people to learn these basic skills. Try to stay out of debt unless it is for school with a useful degree.
