Doesn't matter how much you own or earn, if it's even $1.00 more than what you spend then you are rich.
If you can achieve the state where your long term earnings on your investments are more than what you spend, then you are truly independent and wealthy. You've "made it".
No use saying, for example, that you own 5 houses and a large share portfolio if you owe the bank $3 million......
It doesn't have to be a lot, but the man who has NO debt and can live on what they earn from passive income from investment, is a free man.
