This means that there are opportunities that are missed, chances that are not taken, and dreams that are never realized. Just because we are going through life only half-awake. It is in these dull times that we need to be shaken, to be given a shot.
This thought reminds me of the Erwin McManus book - Wide Awake. Which is a challenge to life life 'awake'. To take the risks. Notice the opportunities. Take advantage of the life happening all around you.
Today is an AWAKE day. Grasp it.
