From a psychological standpoint, what does "falling back to Earth mean"? Is it the sudden lack of public recognition? Is it the sudden lack of energy that feeds the personal narcissistic trait? Is it acceptance of defeat because the artistic viewpoint wasn't able to evolve with the times, therefore feeling "deprecated"?

Ultimately, if the goal of an artist is to feel great in the eyes of others, is it the sudden lack of purpose? Shouldn't an artist that believes in their own art, be happy in the good and bad times, since their artistic output is all they need to find purpose?
