I've been interested in languages and language learning since 2005, even though I've had the luck to live in a multilingual environment since I was born.
Languages I've learned or at least explored:
Sometimes, I think that learning languages is the most stupid and hopeless hobby ever.
However, I'm still willing to do it and I enjoy it nevertheless. It's better than much of the other stuff I could waste my time on.
I wish I could remember a word and it's meaning by only reading it once. Unfortunately, memory doesn't work like that.
Context, context, context. Use the world in real settings.
I want to all know words. Even the useless ones.
I want to know how you say “plough” in your language, even if I haven't even seen a plough in my life, in any language. I want to know, because knowing what the word for “plough” is, how it declines, where it comes from and what its phonetical structure is, tells me something about your language, and about you, native speaker of the language.
Repetition is good for learning words. You can call it the mere exposure effect.
