The first thing is to have certain professional knowledge (the major here does not refer to editing knowledge, but to disciplines). Without a certain professional background, it will be more difficult to communicate with the author. Secondly, you should have some writing skills (of course, this ability can be accumulated slowly in the process of work); Third, editors should be quick-thinking and good at learning, which is also crucial. Editors may deal with authors from different industries. Without strong learning ability and agile thinking ability, it is easy to get narrower and narrower. Finally, editing is a job of "making wedding clothes for others", so it needs to be able to withstand loneliness and poverty. Editing is a challenging job, and a good editor needs to be cultivated through a lot of experience accumulation. I hope this idea can help you.
