You're probably right about it being to do with the industry aspect of it; at the very least, there's something rather difficult about dealing with the almost incompatible demands of your own artistic/creative reasons for being in the business and the client's grounded, mundane purpose in hiring you. I was never happy - well, seldom - in business; I enjoyed the brief moments of photographic work but hated the restrictions on that and the getting of the opportunities in the first place...
Folks worry themselves silly about what to put in their 'book' to entice clients. My ironic experience was to be hired on its strength, often, but seldom allowed to soar with my own goddam eagles! In fashion, where it was cool to have nice movement shots of swirling skirts, heads half-hidden in background flair, all that sort of editorial stuff, the reality was: I want to see ever stitch. Period. So what do you do? You do what you're told. Or there's no next time. The best chances I got to do as I pleased were when I departed for the calendar world; best pasport out I ever had. Okay, with some calendars; others were about as restricted as was the fashion, but the good outweighed the not so good. And it got me the hell out of grim Glasgow several times a year. They tell me it's changed... (Stay in Australia - you did produce Elle!)
With all that effort to find the daily (if lucky) you-have-it-but-you-don't going on in your head, no bloody wonder some of the fuses blow!
