What's your longest gap between 'I have a thought' and 'I have something coherent to send'?

Trying to understand where the bottleneck really is.

For me it's usually the moment right after capture — I have the raw thought, but turning it into something I'd actually send or publish feels like a separate, much harder task. Sometimes that gap is hours. Sometimes it's never.

Curious where others feel the most friction: capturing the thought in the first place, structuring it, finding the right words, or just deciding it's "ready"?

Would love to hear real examples — what kind of thought was it, and what got in the way?
