Ok, after French I'm now going for Mandarin.
I think I'll have more success now because I'll manage to do the study from Chinese to Japanese, that's it, I won't abandon Japanese, like I was more or less doing with French.
So for 1 week I watched Taiwanese TV and I'm already getting used to a few sounds. Unlike Japanese, Chinese sounds are really different from Portuguese and I'm finding them quite challenging to get used to.
Well, I grabbed this sentence pack (http://smart.fm/lists/132095) from last.fm and used the anki plugin to withdraw them. I now have a deck with 540 cards with 2 models.
