Just choose one, and stick with it.

In my opinion you should ask yourself, whether you want to learn an Asian language or a western one. It would be interesting to know what you are studying, maybe you could benefit from your choice in the future? Or maybe you've always felt a strong interest for ... French cuisine.... German cars? If I were you, I'd listen to each language for up to ten minutes (on youtube etc.) and afterwards read about the grammar and usefulness of each language. And I'd ask myself how much effort I am willing to put into my studies. In the end the decision will be made by you. Good Luck. ;)

German will be easy for learning than French!

If you want to use it for business, learn german. Germany and Switzerland are the economic powerhouses of Europe. It depends on what you like though. But in my opinion, either German or Japanese if you don't have a partifular focus towards french, because Japanese and German have plenty of international media you can enjoy. Japanese with film, anime, and manga, and German with music.

What is your aim? I think you must spend your time with helpful))) German
