yes rightly said. Everything in life has its own positive side. Even mistakes gives us experience.

The most important thing is we must learn from the mistakes and not repeat that.

Additionally there is indeed deep pain is there behind some experience, but its ok as we can't do much on that. We can't go to the past to correct them.

Am really sorry @cherylsonty, if you have any such experience full of pain (though I wish you don't have any such experience) . Don't worry and go ahead.
