More wisdom from the philosopher-king, Marcus Aurelius, in his Meditations:

“Forget everything else. Keep hold of this alone and remember it: Each of us lives only now, this brief instant. The rest has been lived already, or is impossible to see. The span we live is small—small as the corner of the earth in which we live it.”

Here and now. That’s all we have. But how often do we give our attention to the present moment?
