Last week I started on a short story which I got the idea for from an old essay that I wrote for English class. I store it all in magazine files, and it's become quite a few cutouts and texts over the years.
Save everything you write and whenever you need a new idea, revisit your file and be inspired! If you hate everything you write, try to overcome it but why not save what other people have written and be influenced by them?
Keep following your dreams!
