Because sometimes we forget that:
"Right this moment is all we have and it will never come again so enjoy it while it's here" ...
"Yesterday is history, tomorrow is a mystery. And today? Today is a gift. That's why we call it the present." - B. Olatunji
"Look forward to the destination but enjoy the trip getting there."
"Observe... breathe... smell... touch... then do it all over again."
"Enjoy your "self". Right here, right now. If you don't, why would anyone else?"
