Want to get serious about saving and financial literacy. Advice?

I’m turning 23 in 5 days and I want this year to be the year I actually get financially literate. I live with my parents and they’re covering things like insurance till the end of the year, so my expenses are low and I know this is a privileged window I shouldn’t waste. I’ll be moving to the UK to study and I’ll be earning in GBP for a few years so I want to be smart with my money.

I don’t earn a lot yet but I want to build good habits now with stuff like saving, budgeting, investing (when appropriate) and not being dumb with money.

For those a bit older:

  1. What financial advice would you give someone in their early 20s?

  2. What do you wish you had started earlier or done differently at my age?

Trying to play the long game. Please help a girlie out. Any advice appreciated.
