I watched the Billie Eilish documentary, The World's a Little Blurry, recently (highly recommended) and one scene stood out to me in particular.
They were arguing about some song and you could just see Billie's anxiety about finishing a song and how it was causing Finneas a ton of grief.
He wanted to finish a song and then move on.
She seemed a little insecure about finishing so she wanted to keep dabbling on the productions instead of making decisions to finish them.
Can you imagine if her multi-Grammy-award-winning album was still sitting in the hard-drive graveyard?
Oooof, that hurts to think about.
