Yes, learning other languages is still important even if you're good at English. It helps improve your brain's ability to solve problems and think creatively. Plus, when you travel, knowing the local language can make your experience much richer. It also gives you an advantage in the job market, as many companies value employees who can speak multiple languages. Understanding different cultures through language can also be very rewarding.

I don't think it's necessary to learn other languages if you're good at English. English is spoken almost everywhere, and most business and academic communications are in English. Learning another language takes a lot of time and effort, which could be spent on improving English skills further. Plus, with technology like translation apps, you can easily communicate with people who speak different languages.

It really depends on the individual's interests and career goals. For some, learning a new language might be a hobby or passion. In certain regions or industries, specific language skills might be necessary. People living in multilingual communities might find it beneficial to learn other languages. Ultimately, the need to learn another language varies based on personal circumstances and aspirations.
