"How to Win Friends and Influence People" really helped me understand where I was running into problems when interacting with people. It was written mainly for those who are in sales and need to learn how to persuade, but I've found it overall helpful in my career (not sales). It's one of the three books I would recommend for those who either manage people or are customer-facing (the others being "Nonviolent Communication" and "Carrots and Sticks Don't Work").
That said, I don't really observe the book's dogma in my personal life. To an extent, it has basic advice that's good no matter what. On the other hand, carefully speaking to make someone like you and to persuade them can be awfully inauthentic. I've learned to be careful about being rude or pedantic, but I'd be lying if I said I didn't enjoy a good argument. I like it when I disagree with people. I like to dig down into it with them to uncover the truth. I like to share the truth that I know with others, and I really like it when someone helps me discover a truth I didn't know before, changing the way I see things.
Unfortunately that means that, while I try to avoid it (without sacrificing authenticity), I will be perceived as unlikable to some. This tends to be people who hate confrontation, those who are maybe a bit insecure about their beliefs, and those who tend toward valuing what the group thinks opposed to what the individual thinks.
