Better in time

I remember that Albert Camus once wrote: "Blessed are the hearts that can bend; for they shall never be broken".

But then I wonder, if there's no breaking of hearts, then there's no healing.
And if there's no healing, then there can be no learning.
And if there's no learning, then there's no struggle at all.
And struggle is a part of life.

So I wonder must all hearts be broken?
