Time is free, but it's priceless.
You can't own it, but you can use it. You can't keep it, but you can spend it.
Once you've lost it
you can never get it back.”
So interesting visually. It reminds me of one of those vases/faces pictures where what you see depends on what you expect to see. The outline of this made me assume it was a clock face. But then looking closer, I can see that it's the back of a windup clock. And yet, based on the outline, my brain keeps wanting to interpret it as a clock face. Thank you for the brain teaser!
