I think the person who has had more experience of hardships can stand more firmly in the face of problems than the person who has never experienced suffering. From this angle then, some suffering can be a good lesson for life.
If you have only education and knowledge and a lack of the other side, then you may not be a happy person, but a person of mental unrest, of frustration. Not only that, but if you combine these two, your whole life will be a constructive and happy life. And certainly you can make immense benefit for society and the betterment of humanity. That is one of my fundamental beliefs: that a good heart, a warm heart, a compassionate heart, is still teachable.
No matter what part of the world we come from, we are all basically the same human beings. We all seek happiness and try to avoid suffering. We have the same basic human needs and concerns. All of us human beings want freedom and the right to determine our own destiny as individuals and as peoples. That is human nature.
To remain indifferent to the challenges we face is indefensible. If the goal is noble, whether or not it is realized within our lifetime is largely irrelevant. What we must do therefore is to strive and persevere and never give up.
