I'm currently a senior developer, but relatively new in the role of a "lead". In my current project, I'm having a kind of co-lead and we have two devs working in our team. So a rather small enterprise.

Now my boss told me, that going forward, I will probably be leading larger and more complex projects (possible rather soon).

Since I'm constantly doubting myself, I would really like to learn more about how to be an effective/likeable lead. I've had too many "leads" who were just dogshit, professionally and as a person. I don't want to be that (at least the professional part).

So, I guess my question is: what helped you? Books, articles, just random hints or strategies? I'll take everything.
