In this life we have we spend reasonable time if not most of our time in waiting.
We wait for our turn to use the bathroom; we wait for a family member to be ready to ride with us in our car pool. Wait for our turn to see the green light for us to drive ahead. We wait for the elevator to open and wait again while it brings us to the floor we desire. We wait for our turn to talk to an employee or a superior. We wait for the time to start working and wait for the day to receive our paycheck. We wait for our time to reach a certain age, knowledge, position until we could do something when the time has come. The list will be endless on our waiting.
