Keep your heart open.

"... and the Lord opened her heart to pay attention to what was said ..." Acts 16:14 AMP

Ask God to keep your heart open to the voices around you.  I believe that too many words are ignored or discounted when they, in fact, could be the words God wants you to hear in order for your breakthrough to come to pass.  

So, ask God to let your ears hear what He wants you to hear, and when someone speaks words that touch the depths of your heart, then that may be your clue to act upon them.
