The only reason I mentioned effective at all is that I don't think it is much fun to be a (knowingly) ineffective leader.
There is, in fact, fun to be found at every level. Perhaps not for every person, but that's life.
Yes, but we are not on HN for such generic advice.
Early in my career I thought that leadership is the end goal and just great, nobody told me that it's a bit more complex. My initial comment just says, guys, it's not getting easier, it's getting harder, much harder. Now we can do a philosophical debate what is fun, what is rewarding, that challenges are rewarding (YES they are) but it's about the fact the managing people is not easy and shouldn't be underestimated, the reward structure is very different than coding and much more complex than eg a k8s cluster.
I mean just check Glassdoor and how many people there hate their boss. It's so easy to f*ck up an org if you haven't any experience.
