Focusing on negativity _ People face problems from time to time; however, there are those who have faced graver trials than others. If you are one of those people who's had your fair share of problems, make sure that you adopt a positive attitude despite the challenges, and reflect this attitude in your statement. Wallowing in negativity will give off an unfavorable vibe, and enumerating all the trials you've been through will no longer make your essay an interesting read.
Conducting a read_through _ A read_through is extremely important. It allows you to step back and examine the points you have made and their relation to the theme and the entire essay. For example, you might discover a certain section that did not help at all in supporting your main theme, or some details that could be better placed in the CV instead. Some even prefer to read their essay aloud or have it read to them so that they can spot lapses or gaps in coherence.
