Jonathan Livingston Seagull

One of my favorite all time book by Richard Bach.
The apologue uses gull as a protagonist who tries to find the meaning of life. It has three sections the first is when he is by himself and trying to push the speed limit and things he can do with flying instead using flying only as a mean to getting from one place to another in search of food. He just wants to know how far one can go. He discovers that he need not be at the mercy of trawlers for food. He can relish sumptuous delicacies swimming meters below the sea. He can travel at speeds which would make birds like eagle fill with envy. He can fly and almost stall over water. The rewards are tremendous. He gets ostracized from the gull society for doing this.
The second part is when he meets other gulls who are in pursuit of similar goals of improving their flight. The metaphor is apposite. Here also he excels while other gulls get satisfied, Jonathan remains curious he wants to know how elder can move from any place to another.
The third part is when he moves back to the community which ostracized him. To give back what he learned. He starts with one guy fletcher who is like him trying to find out about this flying business by himself.
