This lack of motivation means that learners basically don't spend their own time on learning English, and if they do, they don't do it regularly. For example, a typical learner might study English phrasal verbs for 12 hours before an English exam. However, he will not read a book in English for 30 minutes every day. He just doesn't feel that learning English is pleasant enough, so he will only do it if he has to. The problem is that a huge one-time effort gives you nothing, while small, everyday activities will give you a lot.
If you enjoy learning English, you will spend more time on it, and you will do it regularly. A high level of motivation will also give you another advantage. It will be easier for you to memorize new words and grammar structures. The reason is that the brain easily remembers information on a subject that you like. (For example, some people like history and know everything about World War II. If you told a "normal person" to memorize all these facts, they could never do it.) So enjoyment of learning gives you double benefits.
