The right to make mistakes!

Hello folks!

Some of my friends said to (told) me that my English is very good. I don't think so. I don't say that it's a nitemare (nightmare), but I know that I don't master all the English vocabulary, and that about the grammar, I make a lot of mistakes! (and that I make a lot of grammar mistakes) A lot!

But I'm here to learn, to improve my skills, in English, in Italian, in Dutch. I would also be happy to learn new languages: Spanish, Portugese, Japanese...

And to(I) know at least 5-10 words (magic words) in any language I could(know), even if I don't write them correctly. At least I can use them orally(better: at least I can say them correctly; at least I can pronounce them), in order to say "Hello", "Please", "Thank you", "Bye" in dozens of languages. Examples: Tessekur, Obrigado, Sayonara, Dziekouye, Mboté, Gracias, Dzien dobry, Molto mes, Yorokonde, Ni hao, Danke schoene, Arigato.... (all these are different words in many languages)

But, I'm sorry if I talk too much, I'll go(get) right to the point: Are we allowed to make mistakes? Recently, I made a mistake in correcting someone in French. I always have(have always) learnt a certain grammatical rule, and I know from today I learned it bad(wrong), until someone (a non-native French speaker) told me I was wrong, and it sounds(sounded) like it was the end of the world. Not for me but for that person.

Am I allowed to make mistakes? Am I a human being? You shall certainly find a lot of mistakes in my English text, but as a native French speaker, am I allowed to make mistakes in my own mother language?
