OK, so I have previously mentioned about show don’t tell and what not to write and what to write. Here is a tip for when you come to self-edit your work (you do self-edit, don’t you?). There are two words that you can look out for and either highlight or ring in ink to know that you are telling and not showing. They are:
1. In present tense: Am. If you write, I am happy, you are telling. So, instead write, I smile. I laugh.
2. In past tense: Was. He was upset. Instead write, he cried. He burst into tears.
I am sure there are more, but these two are the most obvious to me, and ones that writers often use.
