It’s come to my attention that I’m being very judgmental and jumping to conclusions in my personal relationships. Looking for a book, or an audible, that can help me find peace in objectivity

there's this situation with my son where I didn't feel that his teacher was giving him an equitable shot. And in asking for help, a bunch of my friends have made it clear to me that I'm assuming a bunch of things about his teacher. bad judgments really, and unrealistic expectations. and honestly, it's exhausting to make those kind of judgments. especially since I noticed that I've been doing it all the time and in more situations than just this one. really looking to and ready to grow. religious and spiritual texts, from any religion, also welcome.
