You have to break down in order to break through.
Break down into what Ruchi?
Although i have had heard of Hammering. Suppose an Iron Grid will break through at 12 million hits. Most of people stop at 10 million only. Just continue the hammering. And yes you will break through.
Hope it adds something to the meaning.
I mean.. For do something new you will have to fail many times.
And I am agree with you.. That you are talking about "you should try untill you reach the goal".
