I entered the College of Agriculture and studied trees, grasses, flowers, birds and even insects. I still remember the names of hundreds of species, and whenever I find a tree or grass I don't recognize, I enjoy trying to identify it using a classification book.
We didn't have to decide on a major until the second year of university, so I didn't study at all as a first-year student, spending my time having fun instead of going to classes. Following that, I thought that forestry would be interesting, and so I decided to take that for my major. Even though it has nothing to do with my current job, I'm glad that I studied forestry, as I learned a lot. There are many trees that I do not recognize in Japan, but I intend to learn their names too, it's a hobby that I really enjoy.
When I retire, I'd like to become a forest interpreter in South Korea. I could take children on tours of the forest, teaching them the names of the trees and flowers, and the stories behind them. But that is something in the very distant future.
