To answer the question included in the title of this article...YES!  There is so much more that goes into creating art than the act of creating it...if you are trying to make a living doing it.  It's a job, much like being a farmer. 
 The creative process is like producing a crop.  But that's not the end of it...then you have to get your "crop" to market, and hope to find the right buyer, and hope that demand is high, so that you can get a fair price and hopefully, one day, break even, to help pay for all of your inputs(in farming terms: fertilizer, seed, equipment, fuel, feed, building maintenance, equipment repairs etc) in artist terms, (canvases, paint, pencils, supplies, brochures, business cards, booth setup(tent, walls, hardware, print bins, tables, tarps, flooring,) web hosting fees, jury fees(just to be judged so that you can pay again to be in an art show)booth fees(to be in the show), fuel to get to the show, hotel expenses, food, advertising, wear and tear on your body from loading and unloading your booth and merch,and much more that I am forgetting.  
And then, after all of that effort, the artist, much like the farmer, planting time is like setting up for a show at an art fair...you get everything loaded and ready to go to the venue (for the farmer, getting the planter set up and heading to  the field) you pray for good weather, so that you can get your crops in, (booth set up).  
Then, like the farmer, the artist begins planting the seeds(talking to potential clients, handing out brochures, collecting emails) . 
Here's the part that's most like farming.  After all of the "seeds" are sown, we wait.  We might not sell anything at a show we traveled hundreds of miles to be in. To be honest, I did not sell a single item at the South Haven Art Fair, and that's ok, because I met lots of really interested potential clients.  Like the farmer, we wait for months, and hope for a good crop...(for the artist, a sale or two, or a commission to create a custom piece).  There are no guarantees, just a lot of faith that things will work out, and something will sprout and flourish and provide something to sustain us until the next season arrives.
Why am I telling you this?  Not for you to feel sorry for the artist.  I wouldn't be doing this if I didn't love what I do.  
I am telling you this so that more people will understand that artists, are more than creative types who live this idyllic life and paint all day.  Much like the farmer or any small business owner, we wear many hats that involve things like: accounting, marketing, advertising, designing, carpentry, sewing, creating, custodial, retail, blogging, public relations, the whole can of worms!
Much like farming, selling art is hard work.  I have a friend who once told me that she selling art is harder than closing a multi-million dollar deal at the corporate level.  I don't know why I still do it, or how to explain why I love being an artist....except much like the farmer...it's a labor of love.  
CHEERS! To all who create, farm, or do anything they love even if it's the hardest thing they've ever done!!  Persist and  brave on, my friends!
