If I knew that my business would give me the same amount of income as the bank did, I'd probs go self employed. But the career path pretty much ceases at that moment, and the earning potential stops along with it.
There is enough work to start a franchise of my own out there...honest. Or just put on staff.
I CBF for now

But yep, income is dictated by hours in the day.
If you only look at income that way.
The value I have added to my place counts to me...as does the time I have to 'live'.
I stopped chasing money as a 'life goal' years ago...waited tables on too many Rich peeps to want any part of it.
