Hi Andrew :-)
Here`s a post
you might enjoy, about what kind of business would someone start.
When you say the art industry is pretty much already fully evolved, I think you`re missing the boat. That`s like saying that an octave has only 13 notes, and they`re fully evolved, therefore there can`t be any new music. :-D Y`know?
Art generally categorizes into a couple of very broad aspects. There are people who create art, there are people who support art, and there are people who broker (sell) art. Agents would be people who both support and sell art. So too, gallery owners do the same.
You say your skills are mostly typical, so I`ll assume you`re not an artist. But that means you DO have something most people totally fail to consider valuable. You`re "average," so to speak, and I don`t mean that in a bad way!
There`s a great story by I think Mark Twain (although I`ve yet to find the damn thing). It`s about "The Common Man." In the story, people all over the world are trying to figure out the best average for things. So they want to know what would be the average shirt size, pants length, food choice.
When it turns out that this Common Man is perfectly average, the whole world comes running to find out the answers to these critical questions.
Now think of the world of art. It`s dominated by intellectually elite snobs in many instances, shutting out all sorts of other people. Lots of people really don`t know enough about art to go into a gallery and buy something. They believe they`ll be laughed at, condescended to, or otherwise turned off.
People say, "I don`t understand art, but I know what I like." The "industry" then makes those people feel foolish.
What if you were to build a business that brings art and understanding in to the more typical family environment? You could educate people, talk about art appreciation, or do reviews of types of art. You could write, blog, or make recommendations.
What`s actually your passion about art? How does that manifest itself in your everyday life? Don`t you think that thousands of other people would wish they had that passion? How can you make a connection between your passion, and people who don`t have the time or understanding to gain what you already know?
