I can see clearly now the ______ has gone

One of our difficulties in portraying truthfully as actors is our child defense mechanism of protecting the ego.  No one wants to be wrong, the other kid is the dummy, I know all the answers, and I will let you know that I know what I know. These are all opinion based judges in your own head, nonetheless, a reality of how our brains work.  If we were able to "detach" ourselves in the process of creating, quieting this voice, (not to a total silence, as you will later see in your growth, that this voice is a truthsayer - for all my Dune fans) it will allow you as an actor the freedom to be wrong and receive the precious gifts of artistic accidents, which is your mind in hyper speed giving you the answers.  A mental and physical exercise to jump start any scene work and to assist through this process is to imagine someone else doing the scene.  This is particularly fun to do if you see in your mind's eye perhaps one of your favorite actors; how would they do the scene? Listen to their voice, see them getting what they want. This allows you not to be personal, it is not you putting your heart on the line, but someone else, and you can observe that, almost like a scientist.  Did you like what you saw, would you direct them in any particular direction? Another exercise is to switch characters with your scene partner. It can be male, female, does not matter.  Once you have rehearsed a scene for a while, switch parts with your fellow actors.  They will show you things you have not seen about yourself - eye opening to discover how they see your character.
