There are a few things to keep in mind when choosing which language

you want to learn:
Why you want to learn the language. Your personal motivation is crucial for your language learning success. It's highly recommended to study a language that you are motivated to learn, whether it be for personal or professional reasons.

Where that language is spoken. This can help you figure out your best strategy to be able to practice the language with native speakers as much as possible and can determine how practical the language is in your life.

How knowing the language can improve your life. Once again, the more a language can help to improve your life, the more motivated you will be to learn it. The more motivated you are to learn it, the easier, more fun, and faster it will be to learn the language. Choose a language that will bring you fulfillment.

Know what resources are available to you. Some languages are easier to study than others simply because of the language learning resources available to you in your neighborhood, city, country, or online. Studying a language with easily accessible resources can save you time and money and help you to make your studies more varied, interactive and practical.
