A little off topic, but along the same lines as "do something you love and you'll never work another day blah blah". I'm not quite sure if I buy that sentiment.
I'm a professional photographer, and I don't shoot for fun anymore. While photography used to be one of my favourite things to do, turning it into a job turned it into a grind. I thought that getting paid to take photos would be the best job ever. In reality, I preferred photography when I wasn't getting paid. I guess maybe that's just me - other photographers obviously love their work. I shouldn't really complain, since it still is a pretty great job - just not quite what I thought it was going to be. Things could be better, but they could be a hell of a lot worse.
Though being a pro photographer, I have learned what I value and what I will look for in future business ventures. Personally, I don't think it actually matters what your job is. What's most important to me is dollars/hour. Time !=money. Time > money. I would rather work 4 hour days and make 60,000/year than 8 hour days and make 120,000. I want to make as much money as possible while putting in as little time/effort as possible. Is that too much to ask?
This is why I don't like photography as a career - it is all sweat equity and it can't really be scaled. I'm not sure if I like the pressure to perform either. Even though I am fairly confident I can deliver, I still stress. Selling an art is tough because art is subjective.
I guess I don't really know what I'm trying to say here... Maybe this is wrong thread for this post, but I am slightly drunk right now, so you'll have to forgive me.
