Apart from job satisfaction, meeting a variety of people, I can take time off as and when I please, no one to answer to, or tell me what to do.
My last job before going into this business was 9 years army.
This job is a breeze after 9 years of being at the military's beck and call, never having the right to say "no" and literally being just a number, used and abused. (that's how it was during my time, anyway).
This job, love it, I'm in charge.
Dave.
