In the words of the venerable AvE: "Make cool shit, put it on the internet." Have I been able to follow that? Not really, too many other things going on but I think the sentiment is nice.
'cool shit'
who defines that? The reader.
'cool shit' could be about how you feel in a relationship, how you just cooked The Best Food Ever, how your pet made you laugh, a joke, an insightful sentence / paragraph that you read, something you saw, something you felt.
Just write.
If it is useful to you, then just write.
