I lived in Denmark from I was 0 to 2 years old, and again from 5 to 39 years old.
This means that my best language is Danish.
Anyway, there's a big marked if you write in English or even in French. I've started project in Danish, which were a great success, and I've copied them into English, translated them, and started blogs.
So, my idea was to write a blog about e.g. making money online in Danish at Tips og tanker om penge på nettet and in English at Tips to Make Money Online.
Fine idea, but it doesn't work that way. Not for me, anyway.
What happened was that when I've written the post in Danish, it was boring to translate it into English. So the English blog had very few updates.
Now, I've started creating sites in English, but only in English, and I make a lot of progress. I even have started blogs to support the sites. I write on those blogs.
Perhaps it's due to my A.D.D., perhaps it's just normal, but if you want to write in a foreign language, don't do your own language at first. Write only in English (or French or whatever).
