Learning a second language at school or college has obvious advantages of course, such as landing a job, being able to communicate with people from other countries, more ease in traveling to and exploring the country in which the second language is based and so forth. Apparently, it also wards off dementia in our old age. (Ellen Bialystok, Fergus I.M. Craik, Morris Freedman, Neuropsychologia 2007.)
In addition to those benefits, I have also discovered that learning another language opened my eyes to the culture behind the language, and the people and customs of that country (in my case, Japan). Furthermore, it gave me a more worldly perspective, both with regard to different lifestyles and attitudes about life.
Most rewarding of all though, learning another language seems to have sparked my imagination, and inspired me to be more creative, leading me to numerous adventures in Japan, writing haiku and western-style poetry, as well as articles on various topics, and penning my debut novel, Gold of the Rising Sun.
Would I have done all this without learning another language? In a word: no.
