For instance, I found the reason why I have not mastered English yet. It is because although I try very hard to expose myself to English, I never have try make it mine. Which means, I did not try hard enough to have the language in the core of my brain.
If I has mastered it, I could have learned Chibese or Japanese and even mastered it.
Let's try harder. Form knowledge in my brain. Visualize them. Make it yours. They are all yours. Take them.
You got this.
You are very close.
