A lot of learners give up learning simply because they are just not inspired anymore. It is important to keep things fresh if a learner intends to study long-term. Rather than sitting in a classroom or reading a book, there are various computer and smart applications to try. These applications aid in pronunciation and vocabulary memorization. There are also fun games that engage the learner in challenges that help them retain the lessons they've learned.
It is easy to burn out when an individual does nothing but rigorous study with a textbook. It is important to keep language learning a personal and engaging experience. Finding language partners, going to group events, or going out of one's way t practice the language. All these ensure that a learner does not fall into the trap of boredom only to give up. It is a waste not to at least try to mix things up when hobbies become stale, especially once they've come a long way to get where they are.
