This quote is encouraging people to write every day, even if they are inspired by or copying someone whose writing style they like. It is also warning them not to get too caught up in copying that writer. As an example, the speaker talks about trying to write like Ernest Hemingway, only to quickly realize that Hemingway had no sense of humor and didn’t write anything funny. The takeaway message is to write but be sure to infuse it with your own unique style in order to make it truly yours.
