Agreed. My part-time (personal time) side projects are now focused on feature length screenplays. Those clock in 80 to 120 pages. Not exactly happening in just one sitting. Takes time, planning, and also, like you say, being personally attentive and accountable without too much pressure. My third and most recent is my longest 121 pages, and it took approximately 3 months from sketching out (based on short stories) to final page final period. I can definitely state that there were 2 week stretches where it didn't get touched at all - either due to writer's block about something or 'just not feeling it' but I found my way back time and again and glad to hit the finish line that I'd set for myself.
