As a student, how we can learn our lessons effectively is a common problem which is always puzzling us．If you follow suggestions below, I'm sure you'll find the solution easily.
Your interest in the subject is the essential driver of success. You can' t learn what you do not want to learn. Emotion is an important part of the learning process. If you are even moderately interested in a subject, give yourself a chance. The key is to get started. If you can create some pleasurable routines, you may find that the subject grows on you. You must always remember learning is just like eating. You don' t expect to enjoy your food without appetite（食欲）.Therefore, you should always try to arouse your interest and desire for knowledge if you want to learn well.
Don't expect to understand things, or remember too much, the first time you study them．Think about what problem you will meet with in your study, so that you are well-prepared for it. Never be disappointed no matter what happens. Trust that things will get clearer as your brain comes to get new information. It is like a jig-saw puzzle or a cross-word puzzle（纵横填字游戏）. As you start to put the pieces together, or string the words together, the full picture becomes clearer. The brain learns all the time, but on its own schedule．Learning does not take place according to a schedule laid down by a curriculum or teacher. Keep at it, and you will gradually find that things that seem difficult at first, will become second nature with time.
Your brain is struggling to form patterns to cope with new input from your learning activities．Sometimes, no matter how long you focus on one subject, your brain is not going to pick it up．If you are stuck, move on．Then cover the same general information from a different source, a different book, or a blog, or an online lecture or a video．Try to become a grazing learner, wandering about the countryside, rather than a feed-lot learner, just standing there in one spot, chewing the same bale of hay．The broader your base, the easier it is to learn．Just as the "rich get richer" , the more you know, the more you can learn．
Take full advantage of the Internet, blogs, and various mobile devices, not to mention good old-fashioned books and magazines．Learn during "dead time". Listen in your car, on the train, or while jogging. Have your learning with you while waiting in the doctor's office, or listen while checking out at the supermarket. Anytime is learning time．Remember, you are learning through exposure, not by nailing things down. It is more like moisture accumulation in a cloud, rather than building a brick wall．
The "loneliness of the distance learner" is a thing of the past．Join a learning community on the web, where members share their knowledge and experience. Search for the communities that suit your interests and learning styles. You will find encouragement, advice and stimulus from fellow learners, as well as from tutors, teachers and coaches．In these communities, you can measure your progress against your own goals, or compare your experience with that of other learners．You can even teach and help others, which is a great way to learn.
