Know when you're being stonewalled. Seek dispute resolution.
Dispute resolution is broken. If you can’t resolve a dispute with an editor, ask for a 3rd opinion. When that 3rd opinion fails to resolve the issue, open an RfC, vote for your option, and forget about the issue for the next 2-3 months while the RfC concludes (don’t forget to reopen and update the RfC date once a month.)
In short: Wikipedia is better the less you’re invested in it. Be a gnome.
