Impeccable

I am rereading The Four Agreements by Don Miguel Ruiz. His first agreement —

“Be impeccable with your word.”  

Ruiz calls this the most important and most difficult of the agreements.  I’ll have to ponder that, but it may also be the best 5-word bit of advice ever given.  I looked up “impeccable” and its  synonym is “faultless.”  That faultlessness is (in my experience) an unattainable goal is beside the point, or maybe that is his point.  That is, we all need to be impeccable with our word because none of us can be.
