Art shows are a mystery and one of the biggest questions is attendance. Without visitors, there are no sales. No sales no artists and no artists mean no event
Whether you want to be an artist or travel the world abroad; make sure you are doing what meets your priorities. Just because you want to travel, doesn't mean you are wrong. It is right for you. Making art is right for me.
Not all "Great Venues" are perfect for everyone. If they were, you would see crocheted salad forks at every show you did. Look at which displays that are getting traffic and think about how you might be different.
Keeping your options open is fine but sometimes you can find yourself letting someone down that was really counting on you. You can burn some pretty serious bridges that way.
What do you do when you don't feel creative? Sometimes getting started is the hardest part. Putting your pencil/brush/pastel to the surface can get you moving on to something greater.
