Part of my benefits include budget for professional development. Some things I can use it on include books, productivity tools, courses, training, coaching, etc.
I've spent approximately none of it, and I have the impression that there are some things out there that could improve my productivity/wellbeing/skills that I'm not aware of. If I can turn some of this budget into skills that will help me for the remaining 77,000 hours of my career, that seems worth exploring.
What are some things that I should consider using my budget on? Bonus points if you have firsthand experience doing this thing, but I'm happy for more speculative suggestions (so long as you highlight your uncertainty if that's the case).
I should also flag that some specific things I think I'd like to improve on are generalist research skills, epistemics/critical thinking, writing, and overall productivity.
