Ask HN: What's the last non-obvious skill that made you better at your job?

Emotion management. I think this is more subtle than having a stoic front to everything. There are places/times where showing bare emotions moves the needle forward for example inspiring people, driving home a passionate point and sometimes in conflict, yes conflict, there are people who only understand emotion like anger to see the errors of their ways, for these folks reason doesn't work

And in other places/times, gulping down your emotions and being stoic is all that matters. Also no one likes a person who is inert all the time, so there's also prepping for that.

Not sure this really counts but “curating” social media feeds to follow high-signal ML researchers and devs to keep up with the latest trends, ideas and papers

Writing a blog. Many of my posts are things I've learnt at work, or arguments I've failed to make it meetings. By writing it down, I can pin down the argument better and share my thoughts in advance.

Patience and empathy. I was never going to be a top performer, but I understood what stakeholders were asking for.

No offense .. to ask proper questions and to say no
