Dan Tamayo asks about resources for "project management, mentoring, time management, or other important skills in academic jobs that academia doesn't necessarily train you for."
First, an answer:
What's really hard about this question, I think, is that academia is a distinctive and special sphere, and an academic ought to take advantage of the best of it while overcoming the worst of it. What I have in mind is:
Some think that academics should abandon academic work styles and adopt habits like those in the (non-academic) business world. That can't be right: the whole point of being an academic is to benefit from a distinctive and special environment. My habits, here on the outside, might not be right for someone on the inside.
Wherever you are, however, it's worth thinking about the distinctive productivity dangers of your environment. (Programming in big tech has a ton of these; I hope to write about them some day.) Academics might consider working extra-hard to assess the long-term value of their various outputs (see #3 above) and work on abandoning less-promising projects (see #2 above).
Matt Might writes wonderfully about this subject.
