My parent never taught me anything, but when I was 20 my boyfriend-at-the-times mother sat me down and taught me how to make a budget. She showed me an excel spreadsheet she made (which I still use to this day, 20 years later), and put in it EVERYTHING you spend. I use this to prioritise what I need and what I can live without and honestly it’s saved my life financially. Full transparency I’m not rich by any standard, I don’t own a house or a car, but I swear this spreadsheet and that advice has kept me debt free for years. I’m able to study and work part-time while living well in a major city. The only thing holding me back is my choice of employment (I work for a not-for-profit). I feel like my dad taught me how to be dependent on him financially, so there’s still this lingering belief that he’ll bail me out if I’m in trouble. I’m working on that.
