Write as though you were telling a friend. This method helps build rapport with the reader. Use the same enthusiasm. When you write in active voice, your sentences are livelier and shorter. Passive sentences are wordy and often delay the true focus of a sentence.
Active sentences are far more immediate and direct.
It is impossible to make all sentences active. Write the way you speak. Do whatever you like to make the stories highly readable. They are mainly found in the first paragraph of an article. You may use a contrasting font for drop caps.
