Listen to the news, there is always a focus and analysis on what we do not like, want or desire and virtually nothing on want we really value or wish for. We give this negative aspect our added attention and we mull over this and run it over and over until it becomes a habit. The glass becomes half empty in fact you are feeling that someone else is about to steal it or it is full of so many chemicals that it is not safe to drink.
If we turn these things around life can be so much better, we do not focus on the bad we focus on the things that we want, this means that we start to make more interesting choices and when life gives us lemons we make lemonade. For us as teachers we look not at the exam nerves or performance anxiety but we look at the opportunity to play to someone that we have not seen before and enjoy the feeling of making music.
Great art is often forged in visiting dark places but better to do this as an observer; there is a point where we can put some sort of emotional charge into what we focus on and it becomes part of our belief system but if you are the actor then you can distance yourself from the emotional feelings. I have met a number of people who have become rather screwed up by what they do but not every actor that plays an evil character becomes a murderer! However there are some roles in the theatre which are infamous for their negative impact on the psyche of the actor like the role of Lady Macbeth or one of the witches.
By focusing on what you want and not on what you do not want we can make sure that your pupils believe in their ability to learn and develop and that all things are possible and in that way they will achieve great things.
