What do anda think of suffering?

Has the misery anda have experienced had a positive impact on anda life?

Some religious people in older times put themselves through hell because they believed that suffering cleansed the soul.
And there are those who have berkata that going through suffering is the only of achieving wisdom and greatness.

I myself personally think there is some truth to these things. When bad things happened to me in the past, i used to think things such as "Why do these pointless hardships have to befall me?"
but now i know that those perils did benefit me.

I don't know what sort of person i would have became if suffering had played no part in it.
