I've been leading a team since day 1 of joining the workforce about 8 years ago. Of all the traits you've mentioned above, I can say that I've perfected each one of them except for one and it's a shame that it doesn't come naturally to me.
It's the empathy side that I'm lacking. Well, I haven't asked a sick employee to come report in the office but I've always been less understanding of their situation at times when productivity should be the top priority.
I'd always say at the back of my mind: "I've been sick worse than you are but I came to the office and finished what needs to be finished!" I've been recently pissed off at some of my team members who are too chill at work not knowing what they're going through. I'm well aware that this is an important aspect of leadership and that I should improve or I'll continue despising each unproductive person on my team.
