In korean proverb, theres statement that man leaves name and toger leaves his leather. But I think that both leave changes to this world. I watch a movie whose title is attorney. I thought earning money is just important for living. Unfortunately most persons should earn money for their living. But as peoples live imoroves, we can think about the meaning of our society. I want to be one among such persons. How can we change or improve this world? There will be so many ways. Someones may try to write books. Persons may be activists. Persons may organize thier supporting group. Persons practice their thought as small size near their living. How can I do it? I will focus on my current strong area. And I will learn and study many things about this world. And I will think at all times. I will reduce other unnecessary things as having limited time. And I will monitor faced so many opportunity and try to meet many various persons.
