This theory maps to serious writing projects. While outsiders tend to be very curious about how writers tactically do their job (“Do you write in the morning or at night???”), the hardest part of an ambitious writing project as the writer is managing your own psychology. More specifically, in my experience, the key skill is managing the self-disappointment bordering on self-loathing that can overpower other emotions through the long, hard slog.
