big trees. Things are the same in our real life. The situation is always changing and there is no reason for us to be satisfied with what we have now. Instead, we must develop ourselves to a higher level to be well prepared for the unpredictable future. Without the seemingly “useless” attempts, the giraffe may not survive in
nature. As for human beings, the endless development means a way to a better life. So let’s develop ourselves to a higher level to make a wonderful life. This is my opinion. Do you agree with me?
