henry's PS diary

Actually, I haven’t had a lot of chances to speak in front of many people but I have given some presentations at school. At first, I was nervous when I thought about how other people would see me. However, I realized that people don’t care about other guys as much as I thought and realized practicing a lot can make me more comfortable when I speak in front of an audience.

I live in Dogok, Gangnam, and my school is Sejong University located in Gwangjin near Konkuk University. I usually go to school by bus and subway. First, I ride the bus from my home to Hakdong station. Next, I transfer to the subway from Hakdong station to Children’s Grand Park station. Whether I’m late or not depends on how fast the bus arrives. Once I get to Hakdong station, I can finally arri..

First of all, most foreigners seem to think that we eat dog. It is true that eating dog is a tradition in Korea but we rarely eat dog today except for some old men. Korean people, especially old men, tend to believe that eating special food like frog or grasshopper helps their health. Dog is one of them. However, most Koreans don’t eat dog these days. Second, they seem to think that we are in a ..

You should do many things to become a more confident English speaker. First of all, you should practice a lot. It doesn’t matter how much English you know. You should speak your thoughts in English even when you’re alone. Second, you should never stop learning English to speak English fluently and more natural than before. I think master 1000 sentence class is perfect and suitable not just for m..

I hope my dream house has a music studio and a practice room. Because I like music and drumming and my brother majors in guitar, I think we can enjoy these rooms. Naturally, I need sound proofing for each room. I also want to have a study which has an air purifier, wide tables, comfortable chairs. We can study anything at any time in the best condition. Last, I want to have a roof top where we c..

Germany is out of the World Cup, the fourth defending champion in the last five tournaments to be eliminated in the group stage. The four-time champions lost to South Korea 2-0 Wednesday, allowing a pair of injury-time goals while knowing a 1-0 victory would have been enough to advance because of the result in the other group match. Germany ended up last in Group F while Sweden and Mexico advanc..

I was in New Jersey last year as an exchange student. In early March, there was spring break for about a week. I went to Miami with my friends. Miami is located in Florida, which is in the southern part of the USA closer to Cuba. Even though New Jersey was still a little bit cold, it felt like early summer in Miami. I wore light clothes while traveling, so I caught a cold when I came back to New..

After I finished my military service, I started to work at an izakaya restaurant. It was my first part-time job experience, so I was excited to meet new people. I served plates to customer and cleaned the tables. Sometimes people left their food almost completely untouched. We brought that to our kitchen and ate it. It was on the house! That’s when I felt happy during my work time.

A person who I look up to in life is my father. He has carried my family for his whole life. I learned a father’s responsibility from him. Also, I look up to his career. Even though he started his work seven years later than his peers, he didn’t care about that. He’s finally became one of a kind in the global business consulting field. I really respect his tough mind. He certainly believes that ..
