Not sure if this is connected, but 'fossilized errors' is when an error becomes a habit of speech in a second language learner. This happens especially when the error does not interfere with communication, and hence, the speaker does not get corrective feedback.
This has happened to me quite a lot with my Japanese. I really have to pay attention to my own mistakes!

Ganbarimasu!
Regarding learning a language and individual difficulties, absolutely! We all learn differently and this is why all the text books emphasise contextualised multi-skilled and multi-approach activities to try and maximise the chance that any given learner will respond well to the target language in some form or another and increase the chance the language will be internalised. It really is interesting, language learning. I know my wife has an extraordinarily good ear for languages in that she can hear, internalise and use a phrase quite quickly though perhaps with a small mistake in pronunciation. She can even do this long after she first encountered the phrase for the first time. I on the other hand can repeat with very good pronunciation but will forget quickly unless I use the phrase myself soon after I have encountered it, in a very meaningful context.
Anyway, language learning is tough, no doubt!
