To paying attention.
To pay attention. To pay.
French people would say "porter attention", which can be translated as "to carry" attention or "prêter attention", which can be translated as "to loan" attention.
I think it says a lot about how attention is a treasure we sometimes give up too fast.
The attention you give to something outside of yourself, therefore something you could never control, is a currency you pay you will never get back, your time.
Wherever attention goes, energy flows. So whatever you focus on, grows. Choose wisely !
