Colloquially the phrase ‘yesterday’s news’ refers to something which is no longer significant, or perhaps even more strongly, may be used to imply that something which was once important is not anymore.
Yet at the same time, if you watch or read the traditional news, most reports are in fact about yesterday.
There’s an alternative:
You can proactively write yesterday’s news before today (or tomorrow) begins.
I do a version of this every morning, with a good friend.
You can do it with or without a partner, and you can even do it at night before bed.
What will today (or tomorrow) be like? What will you have accomplished? How will you tackle it?
If you’re not thinking about this, then most days may just end up like … ‘yesterday’s news’.
