Without pain and suffering, there is no way of life.

Without pain, there would be no suffering, without suffering we would never learn from our mistakes. To make it right, pain and suffering is the key to all windows, without it, there is no way of life.

Every one of us is afraid to experience pain. There are times that all we could do is to cry it all. It's hard to suffer through all the sadness that we feel. It seems like it's the end of the world.

Experiencing pain has a good side. It teaches you lessons in life. It helps you understand that you won't be happy all the time. 

Remember the quote "Experience is the best teacher."? 

That's true. We won't be who we are right now without the experiences which made us strong. All of the experiences that we had, whether sad or happy, would bring us memories that we could look back into. They are the ones which formed our personality. One who had experienced almost every kind of emotion is a lot better than someone who has been happy all the time.

It's a must that one had been hurt in the past. That would teach him the essence of happiness.
