Efforts / struggle is hard work to realize the ideals - ideals. Every man has to work hard to continue his life. Much of human life is the effort / struggle, the struggle for life and human nature has been. Without the efforts / struggle man can not live a perfect life. If people want to be rich, he had to work hard. If someone wants to be a scientist, he must study hard and follow all academic regulations.
The hard work is being done with the brain can / science or physical / personnel, and it could be both. Scientists are working hard with a lot more brains / knowledge rather than physical / strength. Instead of workers worked hard with physical / strength than brains. Basically appreciate the hard work and enhances human dignity. Slacker caused a poor, destitute and have no dignity and compassion. Because it should not be idle - sit, relax - relaxing in this life. Relax and rest there is a time and a man who set it up.
In other religion ordered to hard work, as well as the spoken hadiths of the prophet Muhammad who was appointed to his followers "Work ye as if you live forever, and beribadahlah you as if you'll die tomorrow".
For the hard work of man is limited by the ability. Due to the limited ability level differences that arise between human prosperity and the other human. That ability is limited to the physical and expertise / skills. People work to get the results a bit weak physically, skill will earn more when compared to people who do not have the skills / expertise. Therefore the search for knowledge and expertise / skill that is a must, as stated in literary expression "Seek knowledge from the cradle to the grave" in education is said to be "Long life education".
Because people have a sense of togetherness and compassion (love) between human beings, the inability of the limited capabilities that will lead to differences in the level of prosperity that can be addressed together in helping each other, work together. If the system is raised to the level of organization of the state, then the state would regulate businesses / citizens sedemian such a struggle, so that the difference between the level of prosperity of our fellow citizens can be removed or not too flashy. This situation can be studied with a view life-style / ideology embraced by a country.
