The collar is like a "RED CROSS" sign for souls.    A tiny little discomfort for the constant work of God and needs of souls who perhaps don't come by the Church at all. 

What did Jesus say?  My Father is always working, so I am at work.” (John 5)

And from yesterday's Mass, since I am sure the words of the Psalm are still echoing in your mind and heart:  "...seek to serve him constantly"

[The conferences that you go to are reported here, so that's not a very good counter point. ]

As I said, some priests choose to sacrifice just a bit and "not relax" all the time, giving the world a constant image of the eternal by their dress and tiny sacrifice.

Little but constant generosities!! Little yesses. 

Maybe one of the reasons why we have so much discord, rancor, and ugly dissent is that "we relax" a bit too much, walking away from a tiny bit of the cross of our chosen vocations.  We focus on ourselves, our comfort perhaps a bit too much.  

Sad that so many have begun saying No.
