It may be important or not. You can certainly cram more importance into almost anything you write. They say write what you know. It may be pretty interesting if you are writing from professional experience. There are a lot of us who don't know much about your field.

Your writing may include more than one of these topics. If you are an adult, it probably will include a few of them over time. If you are very young, you may be having a lot of fun just making up rhymes. If you are in love, you probably are too involved at the moment to have much interest in all these other possibilities. But there comes a time of grief, too, and you should still write.
