Seem like I'm only ever in one of two situations:
A. I hate where I am---it's crowded, I'm out of my element, I feel like I'll be unmasked as a fraud at any time. Or:
B. I'm by myself---and comfortable.
A. I'm making progress. I'm meeting people and/or strengthening existing relationships.
B. I don't have to prove anything. No one sees me. I'm safe. And stagnating.
It's one thing to (A) be afraid and another to (B) give in to fear.
In B, I have the time & space to write, but it's only during A that I'm inspired.
