Why Coast FIRE is powerful
Because compounding does the heavy lifting over decades, the money you invest early matters most. Once your existing investments are enough to coast, you've effectively pre-funded retirement — freeing you to take a lower-paying but more enjoyable job, go part-time, or stop saving and spend more today.
