Every bit of learning is a little death. Every bit of new information challenges a previous conception, forcing it to dissolve into chaos before it can be reborn as something better. Sometimes such deaths virtually destroy us.

When you move, everything is up in the air, at least for a while. It’s stressful, but in the chaos there are new possibilities. People, including you, can’t hem you in with their old notions. You get shaken out of your ruts

When the internal critic puts you down using such comparisons, here's how it operates:
First, it selects a single, arbitrary domain of comparison ( fame, maybe, or power).
Then it acts as if that domain is the only one that is relevant. Then it contrasts you unfavorably with someone truly stellar, within that domain.

It can take that final step even further, using the unbridgeable gap between you and its target of comparison as evidence for the fundamental injustice of life. That way your motivation to do anything at all can be most effectively undermined.
