Was watching an interesting video on YouTube of people talking about their biggest financial mistake and thought I'd be nosy and ask 😁
Mine (aside from having kids 😂) was either:
Taking a credit card out ",for emergencies". It's just amazing what I justified to myself as an emergency when I had that card!
And also taking out a student bank account with a £1.5k overdraft and thinking it was basically free money. Cue the next 4 years of constantly living in my overdraft, my wage not even half clearing it before I spent it to the limit again before the next payday. Sometimes I wish I could go back and give my idiot self a bloody shake.
