My advice on planning for your future
My advice will be boring. Frankly, it all starts with living well within your means. Pay your bills on time. Establish credit early in life by getting a credit card and paying the full balance off every single month. Pay your rent on time and don't risk an eviction. Save for a down payment as well as your retirement by investing.
Yes, these seem like common sense and not a fun way to live today. Delay gratification; it will be worth it. Skip the avocado toast or pleasure trip to Europe on your last dollars.
When was the last time we heard a song on the radio (Spotify for my younger readers) espousing my recommendations? What schools make this part of its core curriculum? Like most of us, you likely didn't learn any of this from society, the media, your school, and maybe not even a parent.
Educate yourself and take good care of your future self. You're going to be that person in the not to distant future. Make sure your future self thanks your younger self (that's you now). Then it will be all the avocado toast in the South of France you can handle (assuming they have that there).
