I've been into English since the second grade of school and eventually got a translator's degree (second higher education). Got mistaken for a native speaker once or twice, which is incredibly flattering 😁 It's awesome to go anywhere in the world and be understood, at least partially!
Apart from travelling and work, English is very practical in many other areas. I love to watch movies in English, to hear the voices of actual actors. Some of them are crappy in Russian (e.g. Doctor Who, you can't translate all the jibber-jabber and maintain David Tennant's awesomeness at the same time). And it's always fun to watch GoT before everyone else in English and have the infinite power of spoiling it for your all friends 😜 Funny thing btw, I noticed long ago that after a week or two I have no idea which language I watched this or that thing in, for me it acts as a self-observed proof against linguistic determinism. There's also one more area where knowing English is very useful. I'm a pirate, and when it comes to old, mainly DOS games, getting one in English is often the only available option. Quality localisations in Russia started to show up around 2000, and before that they were more or less a lousy and messy experience.
