It is always good to use a library more than the Internet research.
Probably most popular one is “How to introduce my essay” or “How to get a good hook.” And this question is smart enough because the introduction will make the first impression of your work. In this case, you need to grab the attention of the reader with a hook.
It is all about the first impression as it is usually the most important.
Writing an essay always was a challenging task for students.
Even when you read different articles how to do your work successfully, you still can have some questions. So, writing an introduction is like getting the main object on a picture captured.
