Im 17 I got a new job a month ago what should I start doing to be financially responsible/ready

Hello, recently i picked up a new job that had a 50% pay increase from my last job. I was making 10/hr and now I’m up to 14/hr and after I’m done with training it’s 15/hr. I want to know what i should start doing so that I can a: save up money for general use b: pay off my car insurance with is about 200/month + gas 15 mpg 18-20 tank size and c: still enjoy the new money that I am making. I currently have a savings account with EECU but i have been spending quite frivolously without another account to store the money away from my main account.

Thank you in advance
