"Neither here nor there" is an idiom meaning something is unimportant, irrelevant, or inconsequential. It suggests that a particular piece of information or point of discussion is not relevant to the matter at hand. The idiom can also be used to dismiss something as unimportant or immaterial.
It first appeared in Arthur Golding’s 1574 translation of a collection of sermons by John Calvin, The sermons of "J. Calvin on Deuteronomie": “True it is that our so doing is neither here nor there (as they say) in respect of God.”

Believe it or not, the idiom was also used by Shakespeare in his play "Othello" (Act 4, Scene 3), where Emilia said: "‘Tis neither here nor there". As such, some even thought the phrase was coined by The Bard of Avon.
Somehow it reminds me of another phrase that WAS coined by The Bard: "The be-all and end-all" ("Macbeth")
I think, as ordinary people (at least for myself 
), our lives probably have much more of the "neither here nor there" moments than the "be-all and end-all" events. The key to be happy is to find joy and learn to enjoy the ordinary and trivial things, IMHO.
Here comes another point: if there isn't "neither here nor there", there won't be any "be-all and end-all". 
Happy Sunday to you all.
