Languages
Your best bet for consistent language learning is to use an app or site and follow a course.
Apps like Memrise (free to use, but sign up so it tracks your progress) will take you through vocabulary, grammar and putting things together in a sentence. It’s in bitesized chunks, so you can learn a little every day, or a larger chunk every week.
You could also use duolingo, or you can use conjuguemos (website only).
