Best handbooks on communication

So I am REALLY interested in improving my skills as a communicator, mostly in more personal relationships like an empathetic partner and friend, but also it could extend to more professional conversations too. I want to take my learning seriously but I dont know which books would be the best so I want your suggestion if you have any.

My goals are to be a more effective communicator in terms of how I communicate my thoughts and feelings without being intentionally hurtful or picking a fight, really REALLY listen to the other person ans focus on what they say, and come from a place of empathy and understanding. I just really want to practice effectively (like actual techniques or steps) on how to communicate clearly, intelligently and nicely. These are my goals. Any helpful reading material you guys suggest? I appreciate all suggestions. Thank you so much for your time!
