Cashflow Quadrant

All of our incomes can be divided into 4 quadrants as shown.
E - employees
S - self employed/specialists (doctor, lawyer)
   - superman (they always do all the things by themselves :p)
   - small business owners
B - big business owners (a system)
I - investors

Heard about 90/10 rule? 10% of the populations own 90% of the $ while 90% of the populations own the rest. Obviously the 10% is come from the right hand side of the quadrants which are 'B' & 'I'.
Hence should you wanna be rich or achieve financial freedom, you gotta do the 'shift'! Shift to the right hand side quadrants!
If it's not now, then when will it be? Not asking you to quit your job immediately, but it's harmless to build up your MULTIPLE sources of income from other quadrants right? Bet you get exactly what I mean.
