Point 1 - Your first sentence should be intriguing, for example, it can be a quote or a link to impressive statistics. Looking for such data, make sure that it is relevant to the type of your essay and it can be related to your story or personality.
Point 2 - In the second sentence, you need to create a hook - write a few words about your idea, but do not disclose the essence to the end. Here you need to create a strong desire to at least find out more about you.
Point 3 - Thesis statement - this is your main idea, which you will justify in the text of the essay. It should be also twisted around those qualities, values or opinions that you will develop in the text.
Point 4 - In the last sentence of the introduction, make a smooth transition to the main part.
