Take the time to learn other peoples’ names.  It always makes a difference.  Others want to be called by their proper names.  It always makes a difference.

So ask the names of people you have frequent contact with.  Do not hesitate to ask their names again and again until theirs are fixed in your mind.  Others always appreciate that.

Then you can gradually become more personal with them.  It might take awhile but you will learn about them quicker if you (first) went to the trouble of (first) learning their correct name.  It always starts there.
