Chinese or Japanese, which one is the best ?

Hi, everyone !

Here the thing : I would like to learn new languages, to extend my horizon and target a large choice of opportunities for my future.

But I think I made a mistake by trying to learn both Chinese ad Japanese at the same time, for I tend to get confused regarding of the kanji signs... So I guess the best is to concentrate first on One language only and start learning the onther later to avoid the confusions.

So, which one is the best to learn first, to your opinion ?

On the first hand, China is a powerful and ever-extending country, offering a large amout of business opportunities...
On the other hand, travelling to Japan is my dream since a long time, and it's clear to me that Japanese is quite easier to learn.

What would you advise ? Have you learned those languages, and which one did you learned first ? What kind of opportunities did you got by mastering Chinese or Japanese ?

Thanks for the help, guys and gals.
