English is the world’s common language. The majority of English spoken in the world today is not between native speakers. Most people who speak English have learnt it as a second language. You can too.
Education is wasted on the young
Learning a second language as an adult can be a challenge but I think it’s better! You have more resources, more knowledge, less fear, and more motivation. It is excellent mental exercise, gives you a huge sense of achievement, and you’ll discover a different ‘you’.
Open up new cultures
Understand how other people experience the world by learning their language. And remember English is not only spoken by people in the UK and USA.
