I was in a quandry earlier this week.  There was something I wanted to do, but felt a reservation about doing it.  I fretted for more than a day waffling between doing this and not doing this.  I thought about the possible consequences pro and con about it and I thought about what I might miss out on if I didn't do it.   ( I tend to over think things *sigh*)   "What shall I do? What shall I do?" I repeated several times over the course of a few hours.  
"You know what to do"  was the inaudible voice in my being.    
"But that doesn't help me, " I argued.  "I don't know what to do--I want to do this but I don't know if I should right now!"  
"You know what to do."  The feeling persisted.  
I decided that the time was not right for what I wanted to do and that I would pass for now, regardless of any missed opportunity.  
And a peace fell over me.  The anxiousness rolled away.   All is good. 
I guess I reallly did know what to do. 
And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus.  ~Philipians 4:7
