Sales in this field and all the other things attached to the rep job make it a tough and demanding job....in actual work and the hours we put in...
Its much harder than sitting behind a desk, pushing papers or being a banker, nurse, teacher, librarian, accountant, psychotherapist, candlestick maker...
You must do it as we are intended to do it (yep, without any "15x15, cheat the system philosophy") to really know the truth.....
Once someone has "work the system" attitude they are worthless to any company...
