After two years of doc writing at amazon, probably Over 1000 pages of content at this point-

Early in the morning, when mind is fresh, not after full day of meetings

Block off 2-3 hours

Caffeine, empty stomach-

Start with first draft and just brain dump. Don’t worry about details.. leave lots of <<fill this in later>>

Start in a notebook with pen and paper only, physically remove yourself from phone and computer, sketch your thoughts on paper and then go to computer to brain dump

Don’t aim for any amount.. no doc is too little

Don’t format, proof read, correct too much at the beginning

Little wine/beer/whiskey can help (but you probably don’t want to do this early in the morning)

Long Hot shower can help you gather your thoughts

Take a break when your brain is fried, walk around, come back to it fresh
