and ironically, i wont give you any direct business advice (maybe someone else will, i imagine this thread will get some attention as time goes on)...because really what you do need right now is to (while understandably difficult) put all that to the back of your mind and rest up.
been out of action for 7 months now, probably 7 more to go. my left arm, i cant lift much on it and its put my neck and jaw into pretty bad shape too. all that stuff is attached i guess. the migranes and neck muscle tension and tears are what get to me the most now.
i havent really got much useful or inspiring words to say, so ill be as blunt as possible.
what you need to do is keep on trucking. find something, anything, and put all of the **** in the back of your mind (paying bills). take it as a learning experience, which right now sounds like bull**** but after the past several months ive realized it really is. i believe stuff happens for a reason, but that may be getting a bit too spiritual so ill skip that.
i also believe that dedication, vision and the willingness to see it all through is all you need to get anywhere. i also realized, just now after reading your post, that the worst possible thing you can do is stop trying, or use this as an excuse to stop trying. granted, take it easy and heal up but force yourself to express yourself even if you dont want to. once a day, write down a thought, something that inspires you.
assistants. i got offers but i have either too much pride or too little to want to take the offers up, but as a pro...you need them. budget for them, include it in your expenses, it is a necessary step.
you can, and will, get through this. dont even give the time of day to thinking about the fact that you wont, or you arent rising as fast as you thought you were, or you anre doing very well.. you tore your tendon. I know how much that hurts. it ****ing hurts.
so lastly, REST. you need it. dont over exert yourself (i did... and I found I was so screwed after that I couldnt even raise my arm past my ribcage for 2 months.) dont even try. just simply rest. plenty of water.
and take up another hobby, that will help you explore your craft in a different way. anything, find something. find something that will allow you to express yourself...it could mean developing your photography, in the long run, in a different way....granted, not right away, but when you are ready to .
(hmm..now that i look at that linked article again, my limited edition work is only available in yellowknife, (northern images). bugger thats a long overdue correction. i probably made the error too. oh well.)
