Just going for a walk often resolves this for me. It often inspires me to do something and gets me into a doing things mode.
Also if it doesn’t, then no harm done. Fresh air and a bit of sun didn’t hurt.
No structures or inspiration needed. Just walk for a bit.
I’ve tried it a few times but so far it made things worse. Knowing there is a timer running just distracts me so much. Like I want to look at it or at least I think about it all the time.
