I advocate this natural learning method with three basic principles.
I. Learning English should follow the principle from simple to complex, from easy to difficult, and from rough to subtle.
A journey of a thousand mile starts beneath one's feet. We should try to avoid pursuing what's beyond our reach in English learning. If we choose and study some difficult, complex, subtle materials at the very beginning with the hope of having better effect, it's proved to be a wrong attitude by practice. If learning materials go far beyond learners' actual language level, such challenges aren't desirable and just make learners frustrated and painful. It's the worst thing that learners' interest and confidence are destroyed by unsuitable materials.
Your thinking will be affected by your mental state. You'll think quickly and memorize easily if you're in high spirit and full of confidence, then you'll get twice the result with half the effort in such a good mental state. Therefore, you should improve your English step by step in your English learning without the wrong thoughts of cracking English within ten days. Language learning is a lifelong developmental process, so don't think you can master English thoroughly only through a period of great effort, and you should know there's no end for language learning.
So long as your life keeps changing, your language, as a rendering tool, will constantly undergo representational redescription, which makes your language expressive level higher and higher. It's natural that you'll attain high degree of professional proficiency and enjoy more and more fun in your language learning.
If some English works seem too difficult, complex and subtle to us, I must point out, it lies in our lack of similar life experiences apart from the obstacles of language itself (vocabulary and grammar). Because we're in too low life levels with too superficial thoughts, it's natural we fail to understand the profound meaning of those articles.
I've been impressed by a statement, "You must learn more things beyond poems if you want to learn writing them." Actually, English learning isn't different at all. You must learn more things beyond English if you want to improve your English expressive level. You're just an outwardly attractive but actually worthless person without enough knowledge no matter how well you've mastered those English language skills.
Actually you can get enlightened by imagining the pyramid shape. The pyramid stands firmly with a big bottom but a small top, and we should use it for reference in our English learning. Complex materials base on simple materials, difficult materials base on easy materials, and subtle materials base on rough materials. The simple, easy and rough materials serve as the big base of pyramid, while the complex, difficult and subtle materials serve as the top of pyramid. We can reach the glorious summit of pyramid if we learn English in this way.
