The most convincing personal statements often consist of your academic records, accomplishments, and extra_curricular activities. It may also include any incredible circumstances, challenges, or adversities you have faced and the manner in which those bottlenecks have been overcome. There is nothing wrong in mentioning about your initiative, inspiration, headship, perseverance, and your ample experience in moving with other cultures. In short, all positive qualities or all achievements in light of the opportunities available to you can be mentioned.
Now you are looking at the remaining 20% of your word limit being your conclusion. Percentages may vary if larger word limits are being offered. Ensure you state why you are interested in this field of study; state the key points from the body of your essay (e.g. accomplishments, experience and interest). Ensure that you keep it brief, to the point and leave out the clichés. Just as you started your personal statement with an attention grabber, make sure you finish your personal statement with one or two sentences that are positive and leave the reader remembering your statement while they are reading the next few.
