Today, write about a secret thing you want to do or be or have. I mean, the thing nobody knows about; the thing so secret that maybe you barely even admit it to yourself.
Write it out fully, then shred the paper to bits and never speak of it again.
Or, yunno, don’t shred it and do something about that secret wish instead.
And, if nothing comes to mind, think about where you sometimes catch yourself daydreaming then pull away by thinking you could “never” do such a thing. Yes, that.
