True discipline is remembering and recovering–inventing if necessary–what interests you. If it doesn’t interest you how could it possibly interest anyone else? ~ Verlyn Klinkenborg
Writing is so much more engaging when it’s about something the writer is interested in.
Notice I said the writer, not the reader.
If the writer is interested in what they are writing about, that interest and passion will shine through, and the reader will be pulled along.
You could write about the various types of carpets, or the mating habits of north American swallows, and if you are interested in it, I bet I will be too.
Find what you love writing, and write it!
