Is it difficult? I like english language so much but I think it's a bit hard to speak. Even more when I try to speak fast, so them my tongue is a mess.

You guys, what can I do to make richer my vocabulary, and what about this question? Did I make a mistake while I was typing it? Be polite. Greetings. If you identify a mistake please tell me.
