If you want purpose in life, you must have a destination in mind.
The Air Show is a useful feature in international travel. It used to be that only the pilot would give you a quick verbal chart of the trip. Now, a world map on the monitors tracks your journey--from start to finish. The monitors give the following information:
Distance to destination
Time to Destination
Local time at Destination
Without a destination in mind, the first three features would be impossible--there would no distance left, time left, or local time to destination. The next three would be meaningless. It really doesn't matter at what speed, what height you travel, what the outside temperature is, if you are not going any place.
Yet your life seems to be a saga of all dressed up and no place to go. You know your ground speed, your altitude, and the outside temperature, but how long can you keep the plane flying?
