Pain=Gain

Once upon a time there were 2 student walking on road, their name were Vicky and Ricky, Vicky was from poor family and Ricky from rich class, Vicky told him to do the homework, but ricky said my homework would be done by my servant and at that time Vicky scold him for this act, Ricky reacted adversely and he just broke the friendship with him, after that Ricky usually came to school and he did show off in Front of him and always irritated him, and entire behaviour change for Vicky, after some period of time there was an examination, and that time Vicky did so much of hardwork but simultaneously Ricky was not preparing for exam and all the time he just enjoying parties and outing with friends, then 1 month later results out 

Vicky got 1st rank, and shocking thing was that Ricky failed, he was crying here, Vicky supported him, then Ricky realised who is true friend, he apologized him 

And now Ricky needs to repeat the same class for one year because he has not done any hard work for studies

Vicky got so much prizes and scholarship from school.

So that's how if you are not go through with the hell, you will not be having an experience of heaven

On this earth there is no gain without pain. If you want something you have to pass through the pain, difficulties then only you will achieve the gains
