Native language, grammar checks, and never-ending language development

After I write something in my native language – Korean, I usually try to check it with a grammar tool.

The same mistakes often keep popping up, yet I feel very happy when there are no grammar errors.

Although it is my native language, I have a college education, and I read and write, it’s amazing how many grammar and spacing errors I make without really realizing it.

Writing seems to be an excellent way to find weaknesses in my language skills.

There is no such thing as true mastery of a language.

Even with my native language as well as with foreign languages, I keep moving forward little by little.
