Attention is the only currency you can't borrow, print, or refund.

means To gather your scattered attention into one tight beam and hold it on a single thing.

from From Latin com- ('together') plus centrum ('center'), by way of French concentrer — literally 'to bring toward a center.' Chemists used it first for thickening a solution by driving off the excess liquid, leaving only the potent core behind; the mental sense followed the same logic, boiling a sprawling mind down to one dense, undiluted point.
