Money management

Hello guys I would like some advice about managing my money. I am a 23 years old with 0$ in economy.. I am a uni student and will soon start a part-time job. Any tips on how to start investing/ saving this future money. I really have very bad spending habits and I really don't want to repeat my mistakes. I live in Quebec so any tips on money management would be amazing!

Also I am really curious about investing so also any tips and advice is really much appreciated!

Thank you!!
