How worried about money management should I be as a teenager?

So I’m 16 and I’ve been working since I was 14. I make a lot of money for my age but I barely save anything and kinda just spend spend spend. I’ve figured it’s okay since I don’t have bills yet and should just have fun while I can, but I also thought maybe I should try to get into good habits, should I be worried about it? There was one month I spent almost $1000, about $970. I bought concert tickets and an expensive vinyl that I’ve been wanting, also movie tickets and smaller things like food and whatever. Should I just have fun? I’ve started learning about money management and know some about it but is it really worth it when I have no bills? It’d be hard for me to create a budget because my income is super inconsistent. I could make $400 one month and $800 the next. I just need some advice on how or if I should be managing money or just learn as much as I can til I move out on my own.
