I know that artists can work this way too. That's why I have "Believe" signs in my studio. I'm basically an optimistic person, but occasionally a negative thought will creep in and influence my creativity and production.
I know the brain is powerful and that it can make things happen. Case in point.... I often think of someone I haven't seen or heard from in a long time. (I know this has happened to you too.) When I was still teaching, I thought of a student I hadn't seen in a long time and two days later, there he was standing in my doorway.
A while back I was discussing another former student with the artist across the hallway and a few days later there she was, at the Graffiti Gallery opening. Yesterday, I connected on face book with a former student, Samantha McCauley. She said she was just talking about me two days before and then there I was making a friend request. (I hope she doesn't mind..... the picture is the underpainting to a self-portrait she did in high school.)
There are many students that I wonder about. Guess I'll just have to start thinking about them and see what happens.
I also need to work on applying this mental exercise to my art. Ah, the power of the positive brain. (Negative thinking...... get thee behind me.)
