I've read a few short sentences recently that hit home.
I rather like this one:
Presume that others are quietly putting up with your awkwardness, idiosyncrasies and annoying behaviors that you aren't even aware of. Try to do the same thing for them.
(I am sure that I engage in no annoying behaviors. Just ask my family.)
HT to Brother Charles who is, I believe, a fairly conservative fellow who's landed at a fairly liberal university in order to pursue graduate studies. Sort of the opposite experience from mine in seminary. I hope he finds the same delight in conversation and friendship with folks with whom he differs as I did.
