Struggle to gain strength : Metamorphosis

The class was full of students, eagerly waiting for their favorite teacher to come. The topics were the process of metamorphosis, how a caterpillar turns into a butterfly. The teacher came with a matured cocoon in his hand, which was ready to go for the process of metamorphosis. He placed it before the students and asked them to wait for the next couple of hours. He tolds that a beautiful butterfly would struggle to come out of the cocoon and fly in the earth. But warned the student not to hamper with it but just to watch with patience. The eager students were excited to see this process and waited very patiently. Finally it started happening. . The butterfly struggled to get out of the cocoon, with a lot of effort and time  it could able to take it’s head out. It kept on trying to take out the other part of body. With this effort and pain a boy took a great pity on it and decided to help the butterfly coming out of the cocoon which was against the advice of the  teacher. He broke the cocoon to help the butterfly so it didn't have to struggle anymore. But what happened ? A premature butterfly whose body was yet to be built came out. Rather than flying in the classroom it fall down on the floor. Shortly afterward the butterfly died. When the teacher returned, he was told what happened. He explained to this student that by helping the butterfly, he had actually killed it because it is a law of nature that the struggle to come out of the cocoon actually helps develop and strengthen its wings. The boy had deprived the butterfly of its struggle and the butterfly died. Apply this same principle to our lives. Nothing worthwhile in life comes without a struggle.
