I normally dislike lists like this but I like some of these. "It’s usually better to be nice than right." "Nobody gets to their death bed and says, I’m sorry for trying so many things."
At my current place, I made a conscious decision to be 'nicer'. That doesn't mean I'm going to put up with BS or get pushed around, but I'm way more thoughtful with how I approach interpersonal relationships. I've found more success with less stress with this approach than I did with my previous tack. It really boils down to being "nice", or as I tell myself, "don't be an asshole".
