There’s definitely a thing about volume and practice.

I have to read, sift, link and synthesise technical stuff voraciously for my work, and it comes very naturally to bang out intermediate notes to contextualise a new piece of knowledge.

My wider interests seem to work on a much longer cycle - it can be weeks until I see a link or pattern of thought I want to express.

I suspect there are also links to self-confidence. I know that I know a lot in my professional sphere but that equally there are always orders of magnitude more I could know - because I am actively thinking about that stuff most waking hours I’m in the flow a lot of the time.

With other areas I’m often conscious that the others in the conversation know far more (e.g. you Harold on this topic!) so I’m sometimes reticent to add my contribution. And I really struggle with the stream-of-consciousness style of blogging outside of work stuff - none of that ever really feels like something I want to share...
