When a person is asked to write a sample essay about himself, he should write about his strengths, weaknesses, future goals and anticipated reactions to challenges. Because these essays are often written for grades or admission to colleges, the essays should be humble yet persuasive.
Because these essays are highly targeted narrative pieces, individuals should narrow down the focus to three to five main ideas. For example, if the essay is for college admission, highlight academic achievements, extracurricular activities, anticipated areas of study, and two unique personal details. These can include musical skills, speed-reading abilities, environmentally friendly stances, and other pieces of personal information that make a person "come to life" on the page.
It is best to write this type of essay for college admission from a humble stance, and to back up each claim with facts and figures. These can include grades, test score numbers, dollar amounts raised in fundraising activities, and other types of numerical data to support each achievement. Touch upon individual points and end the essay with a summation of how all of the points come together to create a unique story.
After writing the essay, ask trusted relatives, teachers and friends to proofread the piece for typographical and factual errors.
