How FIRE works
Like the name suggests, FIRE can be broken down into two key steps:
This generally involves adopting an extremely frugal lifestyle, working extra jobs and saving or investing every single dollar you earn in your teens, 20s and 30s.
The idea is that if you make these sacrifices while you're younger, by the time you're in your 30s or 40s, you'll not only be debt-free, but you'll have enough money to no longer need to work. You'll be financially free.
