(Warning - I'm pretty busy these days, so I won't be able to post very often, or edit more than once in a while. That being said, welcome, and enjoy!)
I've managed to collect quite a few languages in my life - 10 to be exact. And over the past few years, I've decided I didn't want to be one of those guys who used to know how to speak a language, but can no longer do it. Here is an example of that:
I don't want that to happen, although no TV shows are hunting me down to my knowledge. I want to be able to use a language on demand; I don't want to require days, hours or even more than a few seconds to be able to hold a decent conversation. What is a decent conversation to me? I'm pretty happy with conversation at the B2 level of the CEFR. I've found out that in order to converse comfortably at the B2 level on demand, I need to be right in the middle of the level, and I'll call this B2+.
Now I believe I hear this level mentioned the most when talking about fluency. Others say one needs to be advanced (C1/C2), and that I'm not a polyglot because I only speak 2 languages at advanced levels. To be honest, I don't really care. I consider myself a polyglot, and I'm happy with B2+. But here are my current levels, and you'll see my problem:
English - native
Spanish - C1
Thai - B2+
Mandarin - B2+
Russian - B2+
Japanese - B2
French - B2
Korean - B2
Tagalog - B2
Swahili - B1
I love increasing the number of languages I can speak, and I've added 2 in the past 2 years - Korean and Tagalog. But some of my languages have deteriorated over the years, and I've finally decided it's time to shore them all up and push them to B2+. I expect this to take some time. But when I'm finished, I believe I'll be able to use them instantly when I want, as long as I maintain them once every 3 weeks. That maintenance schedule works out nicely, because that just means I'll need to study one language for a couple hours every other day. The rest of the time I'll be playing with them.
