The Truth About Learning Multiple Languages at Once

Over the years I've heard of people learning multiple languages at once, including Korean. While there are some downsides, this is more common than you may think. For example, there are thousands of people who are learning Korean every day through English, but whose native language is not English. In these cases, what should you know before trying this? Are there any major downsides to be aware of? Are there any benefits? I met with Hyunwoo and we discussed our experiences learning multiple languages, and what we'd recommend to others who are in this situation.
