In a 3 year study discovered by Dane Sanders in "Fast Track Photographers:
THAT'S AN 85% TURNOVER RATE
That's because 85% of photographers don't understand what it takes to run a business financially, so they undercharge and burn out from over-work.
Either that or they have no idea how to price themselves profitably, also don't know how to market, and can't find any clients.
The photographers who LAST are the ones who have profitable pricing so they don't burn out.
