I had a marketing coach for a while - years ago. I swear I learn more from him now than I did then - partly because I let go of being shy and feeling 'unqualified.' I never actually took his marketing seminars because I worked with him one on one. But he laughed as he told me about his intro to the seminars.
He said he'd start each seminar by meeting students at the door of the room and make them, one at a time, promise to leave all left brained, analytical activity out in the hallway. They had to agree to check all judgment and previous ways of problem solving before they could enter the room. These mostly businessmen and sales people walked to their seats off kilter terrified of what might come next.He said he might as well have told them to go sit in their underwear.
For me he said: When you sell your work using the same energy you use to make it, it will flow and everything will come together. So my challenge was to get in touch with my messy, intuitive creative process - but how did that translate into meeting people and being in the right place at the right time? How was I supposed to do that? He believed heavily in meditation and clarity -setting goals with your right brain (as it were) - not your analytical brain. The idea was to listen to your intuition.
Even on this site people may feel this sounds crazy. But this guy (my coach) was selling computers using these methods before he retired rich by the age of 35.
Basically he valued being in touch, paying attention and trusting yourself. He thought too much stock was put in breaking other people's strategies down and trying to walk the same path. He believed the world was more complex and individual than that.
While working with him I decided to go to an art convention in New York City. I got clarification each day - 10 - 15 minutes I'd clear my mind and concentrate on who I was meant to meet or what I wanted to do. When I finally arrived at the convention, I attended a seminar and met an art consultant who shared my stated goals. It was exciting (but unsettling at how well his method worked). The consultant and I traveled to another conference together on the west coast and she hired me to do some work - paying me far more than the cost of attending the convention.
So think about ideas that just feel right for you. Try ideas that excite you, and don't judge yourself. Judging is the antitheses of arriving at the flow.
Believe me, I know how strange this sounds. But I also know that just doing the 'usual stuff' isn't always what it's cracked up to be. I think only about 10% of art galleries are operating at a profit.
Good luck. It's a fun adventure.
