I fear this is great advice. I too avoid writing documents. Or even reading them. I want to have my hands in the code, but it's increasingly clear to me that I need to write more stuff down.
I don't fear writing documents, but i do work with a lot of people who do fear reading!
I've found a really good trick is to highlight key figures or a few standout grabs in the early paragraphs of the text and then to have more substantial higlights towards the meaty parts of the document.
Essentially it's like having the bullet points and full document in one. It;s resulted in a lot of people getting interested up top and being tricked into reading down the bottom.
I had/have the same problem, what helped me a lot was to write down what I've learned (roughly bi-weekly). Another booster was to stick to the same document structure for example NABC for proposals and ideas.
Writing would be valuable to me even if nobody else ever read the documents. I find that writing helps me think through a problem much better, and in the end I have a better solution.
