What do you "come back to" every moment?

Today we start with Danish "enfant terrible" Kierkegaard. In the following excerpt, he makes a eulogy of the post horn from which it is impossible to draw the same note twice. Hence, he employs it as an allegory of the impossibility of repetition:

"Hail the post horn! But the journey is not worth the inconvenience suffered, for one scarcely need move from the spot to be persuaded that there is no repetition. No, one sits quietly in one’s room, when all is vanity and has passed away, and yet journeys more swiftly than one does on a train, despite the fact that one is sitting quite still, Everything shall remind me of this."

"Everything shall remind me of this!" How ambitious! How can one remember moment after moment that nothing repeats itself? That every single instant is unique and hence ephemeral? And why would one want to do so in the first place?!

I used to always keep an eye on my ideas. "The most important thing moment to moment is for me to capture my ideas" and so I ended up with a gigantic evernote and a noting habit. When meditating, the "most important thing" is the moment or activity at hand i.e. my footsteps, my surroundings, the sounds, my movements etc

Whatever you choose to "get back to" moment after moment, my assumption here is, as David Foster Wallace and Bertrand Russell (in "The Conquest of Happiness") put it, that we thrive best once we're able to "bring our mind back" moment to moment to anything we choose to. So here's my question for the week

QUESTION

> What is your moment to moment anchor? The thought or 'mantra' you often come back to

> Did you ever try and choose the "Now" or present moment as a perpetual anchor? How did that go? And if you did find it beneficial, what are you comparing it to?
