Deciding on pronouns to refer to a generic someone is surprisingly painful - Implicit defaults really are important, so I don't want to always use "he" and "his" - But "she" and "her" feels like I'm making a political statement, distracts from the underlying thing I'm saying
I alternate them, but not robotically per-paragraph. Also try a bit to avoid the pronouns at all. Also employ "they" some. I do not push "her" every time it's a male-dominated occupation under discussion, or vice-versa. Instead of guys or y'all or folks: you or everyone or people
