“Which language should I choose?”
No language is “better” than the rest. Your preferences will also play a role in deciding which language you want to learn, but if you’re looking to be practical – there are some languages which are more widely spoken such as Mandarin, English, Hindi, Spanish, Arabic, and many more.
The language which will be most useful to you will depend entirely on where you wish to explore, but one thing is for certain – knowing English will be a massive boost. Despite not being ranked as the most commonly spoken language in the world; it is somewhat considered the go-to language in various countries.
By no means limit yourself to one language, but a hot tip is to improve your English before attempting new ones!
