I would agree with this, but I think for me it's more of an undiagnosed ADHD thing, where I have periods of fabulous productivity where I'm up all night for days riding an endless wave of dopamine, and then other times where it's weeks of feeling stalled and unmotivated even when the next steps should be fairly clear.
