What I mean is, do you charge money for your services or not?
If you are charging for it, than you are a professional. Start acting like it.
A bunch of professional jobs are "creative" content. That doesn't mean you can just slack off because you feel uninspired. I typically give artists a lot of leeway on the time it takes to produce something because I'm nice and I want you to give the best results possible. However I'm starting to think some people take advantage of this system way too much.
Now, I'm a programmer, and I currently hate the project I'm working on (true story). Despite what some might think about programming, it's not any less creative than drawing a picture. There's an infinite number of ways to do things, and most of them will work, but when you're motivated you can often do better work.
Now that being said, I can't say to my boss, "I don't feel like working today because I'm uninspired and the code will come out sub-par." I have to drink a hot cup of suck-it-up, and do my job to the best of my ability. If people can't do that, they shouldn't be selling their services.
Once money gets involved, it's no longer just a hobby. It's a job. You need to start treating it as such, or not try to market yourself as an artist. If you worked for a gaming company as an artist doing concept art, and you didn't deliver the pics you were paid to come up with because you were "artblocked" guess what would happen to you? Just because you produce creative content, does not exclude you from producing it in a timely fashion.
From now on, when I commission something it will come with a 45 day turn-around time, or no deal. If I can't ask paypal for a refund because the artist being lazy, that's gonna be a show stopper. I'm not gonna bother posting up a list of people who owe me currently. You know who you are. If I don't hear from some of you that haven't messaged me in months I'm just gonna report you on Artist Beware.
