In general, the best and easiest way is to write about what happened to you and, if necessary, hyperbolize what happened. You can also take a novel or short story and use it as the basis for your own. The main thing is not to plagiarize, but to use some features of the characters or actions. I often check myself through services like https://fixgerald.com/ to see if my writing is okay. Because then you can get your head kicked in.
