For me, it started with a few books. "Ego is the Enemy" by Ryan Holiday established a great baseline mindset to be in. "Crucial Conversations: Tools for Talking when the Stakes are High" is the most applicable book. It explains in detail how other people interpret your actions, and how to approach a delicate conversation with care. Some in person training helps; I quite enjoyed the sessions my company provided from Life Labs.
