Just keep going, just keep praying, just keep doing the apparently ordinary stuff in front of you, just keep hoping ... and waiting. Patience isn't one of my front line virtues, which makes perseverance a little weak too -- and God seems to value perseverance.
Since so many of the things we hope for aren't things we can assist with very much (e.g. A isn't open to listening to advice from you), maybe the waiting is God's way of giving us a role that we can handle. "Hold until relieved," perhaps. We can't see what good our waiting does; maybe we will one day.
