Thus, when you start to write and involve yourself in the writing process devoted to sharing your life experiences, you begin to live an examined life. Living an examined life provides insight, healing and catharsis. In addition, as reflected in Eastern philosophy, when you heal and help yourself, you likewise heal and help others.
Do not employ writing as a stage to publicly embarrass those who have hurt or wronged you. Being able to take revenge and get back through written words may feel good in the short term, but it may backfire in the long run. While the practice of recording personal events may be a way of understanding enemies or people who have hurt us, it shows a level of immaturity ad comes at the price of distrust from other people who are going to work with us now and in the future, because they may fear getting the same treatment from you. It may be a better course to publicize these stories as a work of fiction. If someone asks what inspired the plot, the proper response could then just simply be a polite smile.
It is also important to remember that if an average person who reads your story, or sees it on a movie screen, television, etc., can identify with the people you are writing about, then you need this person’s written permission. But if the people in your story are not recognizable as specific individuals, because location, age, ethnicity, etc. are different, then obviously you have no need to secure anyone's permission to write and sell your story.
