Yes Lord

I wonder how many times God has spoken to me and I missed it?   I want to be so in tune with the Holy Spirit that when God tells me something I not only hear it but I jump and say yes.  In Acts 9 Saul was busy persecuting the church.  Jesus blinded Saul and sent him to a godly man named Ananias.  When Jesus called Ananias, he said "Yes Lord."  That is because he was used to hearing from God.  I have heard God's voice on many occasions.  Not audibly, but make no mistake, it was from God.  Do I always say yes Lord?  I'd like to say yes but I'm sure I have missed Him.  I want to hear more and see more.
