If you deploy a lot of quotations in your essay, it appears as though several people are talking about the topic apart from yourself. This would downplay your own voice and leaves little room for your own ideas. It is your essay and it should be your voice that needs to be heard, not some notable/famous person’s. Quote as infrequently as possible. So, don’t cram every quote you know into the essay. As a rule of thumb, refrain from using more than 2 quotes in any essay. (One in the introductory paragraph and the other if necessary in the conclusion)
For instance, in my own writing, I have frequently cited the example of the Cuban Missile Crisis to great effect. During the crisis, President Kennedy disregarded the conventional wisdom of his generals and his cabinet in pursuit of his ultimate goal: the avoidance of nuclear war with the Soviet Union. Left to his own devices, Kennedy drew heavily in his decision-making from the diplomatic blunders and brinksmanship that precipitated the First World War, and he was particularly influenced by Barbara Tuchman's “The Guns of August.” With this one example, I can touch on the themes of self-reliance vs. groupthink; and learning from the past vs. repeating its mistakes in a concrete and engaging narrative form. Here are a few other examples:
I always get the same reaction from people when I tell them that I’m originally from a small town in Tennessee called Knoxville. Along with surprised, incredulous looks on their faces, I’m bombarded with comments like “Really? You don’t sound or look as if you’re from Tennessee.” These reactions are nearly all the same because everyone sees me as a typical Californian who loves the sunny weather, the beach and the city. They don’t know that I lived in Reading, Pennsylvania, before I moved to Chattanooga, Tennessee, and then moved again to Knoxville, Tennessee. The idea of my living anywhere in the vicinity of the South or any place besides California is inconceivable to many because I’ve adapted so well to the surroundings in which I currently find myself. This particular quality, in a sense, also makes me a more cosmopolitan and open-minded person. Having already seen this much of the world has encouraged me to visit other places like Paris or London and the rest of the world. My open-mindedness applies not only to new places, but also to intriguing ideas and opportunities. This attitude towards life prepares me for the vast array of opportunities that still lie ahead in the future. From my experiences of moving place to place, I have also come to acknowledge the deep bond I share with my family. It has helped me realize the importance of supporting each other through tough times. Moving from Tennessee to California meant saying good-bye to the house we had lived in for six years, longtime friends and the calm, idyllic lifestyle of the country that we had grown to love and savor. But knowing that we had each other to depend on made the transition easier. It also strengthened the bond we all shared and placed more value on the time we spent with each other, whether it was at home eating dinner or going on a family trip. Now when I think of the word “home,” I see the bluish-gray house I live in now. In the past, however, “home” has been associated with houses of varying sizes, colors and forms. The only thing that has remained unchanging and permanent is my family. I have acknowledged this constancy, knowing well enough that it is, and always will be, a part of me and a unique part of my life.
