I read Team Geek (Japanese edition). Fun to read.
It's interesting book because I am a software developer working with team. I often think about leadership of software development project.
In this book, authors explain about servant leader. I generally agree its idea. Sometimes I acted as a servant person of my team (at least I hope so) but I didn't think I am a leader.
To take leadership aggressively is bad attitutde. Leadership will follow later.
