Very good post.
If you want to be a bad photographer you need to find inspiration here: http://youarenotaphotographer.com/
Excellent site. I disagree though when he says photographers shouldn't burn their finished images and let their clients print them how they want.
I'd much rather spend $3k on my wedding photography, get all the images on disc, then print them myself or make my own albums. I'm probably not the average client as I have a 19" printer at home, and am a couture book and asuka book client.
Paying $2-3k and then having a potentially ballooning print cost with insane markups from the photographer bugs me. Could be that personally I'm used to being paid by the job and not charging per print though.
Thankfully though my GAS has been mostly cured.
I've slimmed down my fleet of camera gear and rent when I need to for specific tasks.
Now my gear list is: 6D, Sigma 35/1.4, Canon 70-200 f/4IS.
Recently I've rented: 500L II, 5D3, 200/2 IS
Down the pipe is: 1DX, 200-400, 5D3, 70-200/2.8L II, 16-35.
I ran the numbers and it makes way more sense for me to rent than tie up capital in gear. Rental is also 100% tax deductible which is good.
