If you already have a plot in your mind, don't force your to start with your plot. ahmmmmm.........set it aside then let your mind focus on your daily life. After a day, think of the experiences you had. You can get an idea from those to start with your story.

*I don't know if its right to tell you this even though I don't write fanfics.....but I'm a writer at our school.*^^~!!xD
