To master English

Hi,everyone.Today,I am going to introduce you how to master English.First of all I am 18 years old,and I am Japanese.And I am not an English master.So in this blog, I want I,who have not reached such a stage,and you,who may have not reached the stage,think about this topic together.When we think about the English skill,it seems it  catagolises into 4 skills,reading skill,writing skill,listening skill,and speaking skill.And many people learn English like this;"I am not good at speaking,so I should study and practice it more harder.".It appears to be rihgt.Of course you can get important elements,when you focus on improving a specific skill.However,is it truly right?What I want you to say in this blog,and What I want you to think are that you should learn more foundamental skill which is the basis of English skills.In short,4 skills are connected each ather,and you can improve all skills at the same time.Then,you will think what it is.Truth to be told,I do not know the concrete answer,but let me tell you my idea.The  foundamental skill is "grammer skill".I know I know you say "Ha! Is it only? I knew it once upon a time!".Calm down everyone."grammer skill"includes grammer skill but imply more broad meanig."grammer skill"means grammer skill and meta cognity ability.Meta cognity ability is to understand sentences from high level of point of view.You can improve this skill by stocking a lot of examples and thinking logically.
