When the realization occurs doesn't matter. Before or after, it makes no difference. It is an inevitability. I appreciate your passion for semantics

, but my point is, whatever we do in life coupled with our perception of our own self-worth and our self-perceived success must not be made subject to the approval or disapproval of an audience. Part of performing is realizing that some will like you and others won't. (Too often though, people get hung-up on wondering what people think of them and they never move to the point where the opinions of others don't matter. Do peoples' opinions matter? Yes, but not once you set foot on the stage). But knowing this fact, we must mature and disregard it as irrelevant. Our performance should stand on its own two feet whether people love it or hate it. It is OUR performance.
Why do we get nervous?
Because we fear rejection and disapproval.
Is your confidence tied up in what people think of you?
If "NO, then good for you. However, a "YES" means there is still some work to do in your performing.
There are four ways of getting dressed in the morning:
1. "I'm going to wear this outfit and I'm not sure people will like it. I really hope they do. If they don't like it, I will feel like a loser."
2. "I'm going to wear this outfit. It may not suit everyone, but this is what I will wear."
3. "I'm going to wear this outfit."
4. "I'm going to wear this outfit and to Hell with everyone else."
When we perform, we should be like the third statement. 1, 2, and 4 are unhealthy.
