I have been recommending this post over and over - in a blog post from 2016 on going from academia to data science (https://p.migdal.pl/blog/2016/03/data-science-intro-for-math...), via email, in person.

It helped quite a lot of people - especially women, who had a mindset that they should accept they should accept the offer. A thought that one can (and should) negotiate was a game-changer. Sometimes they were shocked that an ask for 25% more was accepted with no questions.
