let's just say, you want to learn another language.
The quickest way to learn this language is.
For the next thirty days, you take care you have something to eat, you have enough time sleep.
And the rest of the time, you study.
You don't watch television, you don't go on social media, you don't play any games, you don't go out on party, you don't drink alcohol,you don't take drugs. 你不看电视,不上社交媒体,不玩任何游戏,不出去参加聚会,不喝酒,不吸毒。
