I'm learning Spanish and Japanese. I'm reading books in the language while using a dictionary. I also use apps: HelloTalk, Tandem, this one, Lingo Deer and AnkiDeck. I have dictionary apps for Japanese and Spanish. I also watch a lot of YouTube and read blogs. I listen to music and I'm in groups on Facebook.

Honoka, are you talking about learning a new language from the beginning or in a conversational way? If you already have the basics (which it looks like you do), this blog and website has some great tips that focus on developing your speaking and listening skills: https://realenglishconversations.com/blogs-for-learning-english/ Personally, I found that studying conversations (that were appropriate for my level) was a great way to learn. It allowed me to learn the most common vocabulary, see the grammar rules being used together and to practice listening comprehension.
