I have always wanted to keep growing as a writer，not run in place. （not 前面是逗号时，起并列连词的作用，后接与前面并列的名词、代词、形容词、不定式、分词等）

例如：

I want to see Tom, not John.

I want to see her, not you.

I am hungry, not thirsty.

I want to stay, not go.

I am reading a book, not watching TV.

In Academic Writing，you must always keep to the topic. Never get off the topic.（单独一句，祈使句）
