I’d love to! Ok, let us see if I can drum up some different ways that pain and suffering can be good.
**
“Ying/Yang” **
This is the one you’ve brought up already and disagree with…but I still think it has some value. It’s the “without suffering there is no happiness” type of thing. I don’t agree with this philosophy word for word either, but it does have some merits. For example, some people may struggle with anxiety, and suffer because of it. When they persevere through such an ordeal and overcome it, the peace they feel later in life when they meditate or relax is appreciated much more…because they’ve seen the other extreme. Their suffering has brought an increased appreciation, and a deeper capacity for joy. This is a great example, because I’ve gone through it and can tell you first hand!

This perspective alone doesn’t make all suffering “worth it” but it does give suffering some value. Taking this value in combination with the other values to come may show suffering’s true worth.
Compassion
Compassion is something the whole world could use a bit more of. It’s root words, broken down, are (Com: together or with) and (Passion: suffering). From a personal perspective, having suffered through an ordeal puts one in a much better position to empathize and understand the plight of a fellow human being. It also puts one in a better position to help that other person. Think of a rape victim that sets up a center to help other rape victims, or a rags-to-riches entrepreneur that founds a school to help other low income families. Without their suffering, they might not have the drive, know-how, or emotional capacity to truly give their fellow humans what they need the most. This is also true on a smaller scale. Because I suffered bullying when I was a child, I will be in a better place to help my future children, or a nephew, when they are bullied and having a hard time.
Corrective
Sometimes suffering is simply for our own good, whether we realize it and want to admit it or not. We learn through bad experiences as well as good! The simplest example is when a child reaches for a hot pan and gets burned, or a child fights with their sibling and gets punished. Punishment (inducing suffering) can correct bad or foolish behavior! It can also apply to more nuanced and adult habits and behavior. For example, I can be kind of lazy sometimes…even though I keep busy. I’m working full time, taking night classes, have a baby on the way…but I also have a myriad of hobbies that I love. Right now there just aren’t enough time for all of them, and my class work is coming due. I’ve barely started on it. I’m losing sleep thinking about it. I’m stressed and suffering! Once I get through this (and I’m sure I will) I’m going to do my best to break my bad habit of procrastinating. I’m going to try to prioritize my tasks better, and not take on more than I can chew. I’d rather not suffer this stress, but if I didn’t I would continue with my old ways or prioritizing hobbies and fun over work…and that wouldn’t make me a very good parent. Better to suffer and have my behavior corrected before my misguided priorities affect someone else negatively…or causes me more stress down the line.
Justice
This kind of goes with corrective suffering, but is different enough to list separately in my opinion. Justice is a universal concept that is written in all of us. If I break the law, I must pay. Sometimes having to “pay time” like jail time serves to correct the behavior of the offender, or make the street safer by taking them out of society. But making the offender suffer in some way also serves a sense of justice. Think of someone who was physically or sexually assaulted. They’ll want the perpetrator to be found and punished…not necessarily so the perpetrator can correct their behavior, but to make them pay for what they did out of a sense of justice. This makes things “right” in the victims view, and gives peace of mind for themselves and their loved ones. In a way, making offenders suffer (even lightly) give peace of mind to our society, assuring us our values are rightly ordered. Also, making offenders “suffer” jail time can make our society safer.
"What does not kill him, makes him stronger."
Nietzsche is not the best source of knowledge in my book, but this quote of his will resonate with us as long as there are people on earth for it to resonate with. It is a powerful phrase!
Code:
Several, if not all, of the categories I've mentioned could fit under this phrase...but I don't think I'm smart enough to list ALL the conceivable ways that suffering can be beneficial. However, any type of value in suffering that I have missed I believe can fit under this last section.
I believe that it is human nature (and nature's nature) to survive, evolve, improve, develop, adapt, and thrive. There is a ebb and flow to developments of all types, but becoming stagnant goes against the nature of nature itself. We humans are unique in nature for several reasons, but we are often considered most human when we adapt, learn, create, and improve our lot or that of our fellow human. All improvement requires suffering on some level. The arm that swings the hammer must become fatigued to build a house. The mind must be frustrated and challenged to obtain higher learning. Sometimes both the body and mind must wither with age before enough time has passed for a person to secure the deeper meanings of life and fully explore their area of interest.
