I think suffering makes you stronger and it can lead you to success because if you don't suffer than you can challenge yourself to make your life better.
I do believe so that suffering in life is necessary. The reason being is that, this is actually the way we learn in life. Some people grew up having a lot of painful experiences which became their motivation to become better, to do better in life and to persevere. It's through the painful experiences in our life that we grow and realize that if we don't do something about the current situation of our life, we will never be able to change for the better.
