We do not always have to open a door, sometimes we just need to find a keyhole and allow ourselves passage into the next room.  Some obstacles are far more daunting if we have to overcome them entirely.  Crossing a mountain stream does not always require building an entire bridge or rerouting the stream.  A couple well placed stones or a fallen tree allows us to move on with our journey, unyielding to an impediment that was not our primary purpose to solve.  Make our pathway visible and others will follow.
