To become financially independent then everyone’s aim should be to focus on filling up their bucket. The size of your bucket is irrelevant at first but the most important thing is that it does not leak. Then as you earn money you must budget for what you need to save to invest and then how much you need to live.
Eventually when the bucket is full it can then provide you with an income without physical effort. This will be your retirement or your freedom to do whatever you want whenever you want.
