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.
Being a professional, the buck stops with you and sometimes it stops right on top and jumps up and down on you while it is there. It isn't up to the clients to save the day, you need to remember that they are there to see what you have, not pull you out from under the mess.
Being on the road with other artists, a 10x10 space isn't really that big and we can crowd each other. Respecting each other's boundaries can make the show more comfortable for everyone involved.
understanding that you can get in a professional's way and interfere with the end result is difficult to grasp. Stay with in your circle of concern, and let them handle what is in their circle. You hired them/ entered into a contract; trust them to do their job and get out of their way.
Circle of concern; their job is in their circle, your job is in your circle. We are independent contractors but we need to stay within our lines and not try to do the jobs that are the responsibility of others.
