Writing, especially technical writing. There is an art to writing concise, accurate text that someone can easily follow. Very few people are capable of this, and those that can have a serious advantage in their career trajectory. It doesn't matter what you know, if you can't explain it to someone else.
Any recommendations on resources to learn/improve this skill? I completely agree with you but it seems pretty hard to hone that skill if there's no one to give you feedback. e.g. you write some internal docs but then no one lets you know how could they be more useful/understandable, until someone else comes and re-writes the docs.
Thanks for the ideas!
