Maybe that's the best way to create a diagram for living is to have a machine that has a hundred levers in front of it with a number of screens that provide you with multiple pieces of information. One of the screens is your heart or either your center of feelings. Another screen is your brain or your center of thought. Another screen is your body with your center of physical pain or pleasure. You have the ability to move these levers to increase the pain or the pleasure or the good feeling or the bad feeling or the thoughts or you can decrease them. The problem is that there are multiple other individuals or entities that are providing inputs at the same time and moving those lovers at the same time. Many times you cannot even see what these people are doing.
