It is helpful to know your purpose before you read something because it can guide your reading and help you focus on the information that is most relevant to you. When you know what you are looking for, you can skim or scan the text more quickly and efficiently, and you are less likely to be distracted by irrelevant information. Knowing your purpose can also help you to engage with the text more deeply and critically, as you can ask yourself questions about the information and evaluate its validity and relevance.
