It is a day of leisure and celebrations. But for a lot of others it is a normal working day - they have to toil for the rest to celebrate. Many of the workers, small businesspeople, bus and train drivers and dispatchers work so that we can enjoy our holidays. Most of our dreams are realized on the hard work of others. Their contributions add fresh colors to society. That's the reality of life. But society does not belong to the great and the successful alone. It belongs to those whose struggle never ceases. Their condition may not change much in the New Year. Their achievements, even their existence, may not be acknowledged. But we firmly believe they will never cease to move forward. There should be happiness in the lives of all. Therefore, we solemnly send our New Year greetings to them, to the common folks whose struggle for a better life never ceases. They are humble, but it is their joint endeavor that propels society forward. They may not share the wealth and power they so richly deserve, but their position in society can never be disputed. May they find happiness in the New Year.
