It's been a long time since I've been practicing my writing in English. 

It would be greatly appreciated if there is anyone helping me out to proofread my writings.

Thank you! 

Theme: What have you put the most of your effort into in your student days? 

“Approaching theoretical study helped me enjoy my study abroad life” 

During college, I put my most of my effort <s>efforts the most</s> into the class called “intercultural communication”. Even though I did not have any problem to communicate in Japanese at all, I had a hard time <s>to</s> understanding its culture<s>s</s>. To overcome this difficulty, I decided to approach a theoretical way to research intercultural study instead of going through everything in <s>a </s>real life without a deep cultural understanding <s>cultural part </s>of Japan. In the class, I was assigned a lot of time to discuss with other students what we think about Japanese culture<s>s</s> and people. The professor in the class said that “it shows that you guys are coming from <s>the </s>different countries as a majority of you guys feel uncomfortable and negative about Japanese culture<s>s</s>.” As we had time to share our own ideas about Japanese culture<s>s</s> and the opportunity to get interpreted by the professor, everything falls into place in my mind. I was able to have a better understanding of the Japanese culture<s>s</s> than before. As a result, I could enjoy my study abroad life in Japan way more than before as I made a lot of local friends.
