Wherever there is self-image, there is nervousness.
Because self-image produces outcome dependence.

Is seeing oneself in the third person an inevitable feature of life? In other words, are we doomed to everlasting anxiety?

It depends on whether the consequences of nervousness are acceptable to you.

I’d argue that nervousness is a disease: it makes a performance restricted, cautious and mechanical. The artist is deprived of their full faculties as they turn inward in search of prepared solutions.

Sincere Desire

A solution to nerves is found when person says “I can’t live like this anymore.” Freedom from anxiety becomes a priority. This creates a receptivity to the truths relevant to this freedom.

Consider Mr. Duffy, in James Joyce’s ‘Dubliners’:

“He lived at a little distance from his body, regarding his own acts with doubtful side-glances. He had an odd autobiographical habit which led him to compose in his mind from time to time a short sentence about himself containing a subject in the third person and a verb in the past tense.”

We are enslaved to the task of protecting the image we carry with us. It is an existence of compulsions. Spontaneity becomes like the joke about playing Gaelic football in rural Irish towns:

“During a short break in the fighting, a football match broke out.”

Transformation

Suppose you’re ready. You’ve decided not to accept nerves as "a part of being human." You see the hamstrung reality of living through self-image. 

Now you say, “what can I do to be able to perform with total spontaneity?”

The strength of your desire to do so will dictate the path. This desire has an intelligence which will never be compressed into a piece of “content” in your mind.

It is the part of you that must be spoken to in order for transformation to occur.
