I agree. As I've said in the past:

• Multiple income streams (diversification)
• Passive income over active income (profit from rent, interest, yield, dividends, etc)

If you reach the point where your passive income overtakes your living expenses you're financially independent. If you keep going from there you can not only free yourself but potentially your loved ones as well.

The main mistake I see is people chase the job rather than the financial independence.
