A poem of three lines, with seventeen syllables — five in the first line, seven in the second, and five again in the third.
There’s a lot more to a haiku and its history than this, but for now I’m going to go with the basic, widely recognised definition above.
If I write seventeen syllables about each day, or a moment during that day, and order them into a neat, pretty, little 5-7-5 structure, there surely must be some kind of mental well-being benefit. Mindfulness and Headspace et al are all the rage, so I guess this is my version of the “stepping back and reflecting” exercises they advocate. Mindfulness in seventeen syllables, perhaps. There will probably be days I don’t, but the aim is to do it every day. Even if all that happy-head stuff is complete twaddle, it seems like a nice little thing to do.
