In planning your paragraphs, you must give the Admissions Officer a glow so they will wish to continue the next section. To illustrate the structure, let's take a look at the typical personal statement organisation. The first paragraph will need to be an exciting and dynamic narrative to capture the reader's attention. The subsequent paragraphs should outline why you wish to study for your particular field followed by a compelling powerful final paragraph with strong action verbs to give your reader the final push to admit you.
Remember that tension, like all techniques, is merely another tool for making your writing more vivid and interesting to read. However, if you do use it, you must make it clear to your readers that the events you are describing have some relation to your study topic. If not, they will be confused, will have to re_read to make sense of it and may end up feeling irritated enough to stop reading.
