Here's why:
* Personal Experience: They focus on the individual's own thoughts, feelings, and experiences.
* Subjectivity: They present a subjective perspective on events, rather than a neutral or objective one.
* Intimate Style: They often use informal language, personal anecdotes, and emotional expression.
* Reflection and Introspection: They invite the writer to reflect on their own life, choices, and emotions.
Beyond personal writing, diaries, letters, and memoirs also offer insights into:
* History: They can provide firsthand accounts of historical events and social conditions.
* Culture: They reveal details about the cultural norms, beliefs, and practices of a particular time and place.
* Human Nature: They offer glimpses into the complexities of human relationships, emotions, and motivations.
While they are primarily personal documents, they can have a broader impact on our understanding of the world around us.
