To gain something, you've to loose something.

Sometimes, we need to get hurt in order to grow. Sometimes, we need to loose in order to gain. Sometimes lessons are learned best through pain.

Let me tell you a story, 

Once a professor in the biology laboratory, was teaching his pupils about how does a caterpillar grows to become a butterfly. All children were watching it seriously. He said, "The caterpillar will become pupa and after sometimes, it will first break the cocoon and then spread his wings in order to fly, but before that he cannot fly until he tries to fly on his own. it will take him so much pain to learn to fly, so no matter how much pain will the butterfly feel, no one will help him to fly." Professor went outside the class for some reason. After sometime, pupa broke and a little butterfly emerged out of that but he could not fly at all. One student got pity on him and helped the butterfly to fly. Yeah! Of course, the butterfly flied but after sometime, he died. Professor returned and watched the dead butterfly and said, "He died because you did not let him try the basic thing to do on his own, failing which he couldn't fly anymore."

           So, you will have to go through pain to get to the point, to reach the goal of your life. Whenever you think, this is the last I can try, NO!, don't give up there, try a little bit more.
