Do I necessarily need to finish a book from the beginning to the end to be considered read it?

No, you do not necessarily have to finish a book from beginning to end to consider yourself as having read it. Many people feel they have read a book if they have engaged with its content, whether by reading a significant portion of it, skimming, or reading summaries and analyses. How you define "reading" can vary based on personal preferences and goals. Some may emphasize the experience of completing the entire text, while others might prioritize understanding the main themes or ideas. Ultimately, it’s a personal decision!
