I find myself carelessly being rude to people and getting into stupid arguments, even with strangers. Is there a book that would help shape my mindset to become a less argumentative person?

There’s things that I do that I want to change but need guidance:

* I say rude things and hurt people, only realizing they’re hurt by what I said about a minute after I’ve said it.
* I tend to engage in meaningless, stupid arguments with strangers online. I don’t even know why I do it. Maybe I have superiority complex but I don’t think I’m better than everyone else.
* I find it hard to just shut up and stop continuing to argue.
* I find it hard to connect to and justify someone else’s point-of-view.

I need a book that will guide me and help me become better. I’m not religious but if that helps me become a better human being, I am not opposed to religious books like books about buddhism.
