When you set to create your personal statement for college, you suddenly are not in that world anymore, and you know it deep inside. Seriously, no one from admissions wants to read another essay about how much someone was inspired by Gandhi, or Martin Luther King Jr. No one wants to read your personal statement for college about the first time you played football with your dad, or learning the value of teamwork from a little league game. No matter what you write, the chance is that they have heard it all so often before, and they are surely going to hold that fact against 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.
