I always suggest this book "The Servant" about servant leadership: smile.amazon.com/Servant-Simple-St...
This is about being a leader instead of being a boss, and it's not specifically about being a tech lead but more about soft-skills which are useful anywhere else in your life. For me it was a life changer.
What a great recommendation! It was one of the reasons I decided to create softstuff.tools . So many people end up moving into management and don't get a chance to learn about servant leadership.
