Writing Tip #2: Find your topic!
Is there something wrong with a paragraph in your text, but you don’t know what exactly?
Try to point out the topic sentence. This is the sentence which describes the essence of the paragraph as a whole the best. All the other sentences should refer to the topic sentence and should substantiate it.
Can you find no topic sentence, or do you find more than one? Do you see sentences that are not related to the topic sentence at all? Perhaps you are trying to discuss several ideas in one paragraph. Don’t do that.
