I feel like writing, you know, just for fun, but I am stumped when it comes to what to write about.
OR you could write about how beautiful the world is and how some people show kindness to strangers, especially in difficult times.
Write things down you find interesting in a journal.
Write about your very status, and then how it happens and what you do; doors will get open to new subjects.
Write about not knowing what to write about
Write about what the world has turned into, and give examples of just how terrible it actually is, out of experience etc. etc. I found this an interesting subject, because I want to be a journalist as I get older, that's just a suggestion :)
Write about what you love. What makes you happy? What do you wish you had all the time in the world for?
