The reason we get so upset when we have to wait is because we think the only thing that counts in life is the destination. We want to arrive at our destination quickly, with as few interruptions as possible.
But life is not about destinations. It is about the trip, the process, the going - including the interruptions.
Life is not about finishing the degree so that you can earn a living. It is about learning.
Life is not about hurrying through your dating life so you can find the right person to get married to. It is about getting to know a variety of people and enjoying being with them.
Life is not about hurrying down the highway so you can be the first to arrive. It is about enjoying the trip and being at peace with yourself as you travel.
