over the Aron Kodesh in our Shul it says:
“Know before Whom you stand”
daily as we approach Shemonah Esrei, I glance at these words to help set my focus.
On Rosh HaShana and Yom Kippur when the tefila is much longer, if I 1) get distracted or 2) distract myself – I glance up there to refocus myself.
sugestion:
Write those words inside your machzor or even on an index card.
