"Appreciate what you have."

If I had the opportunity to say something that is most important to every person on the planet, I would say "Appreciate what you have." You never know which kiss will be the last, which rebuke will never be repeated, which conversation will never be repeated, with whom you will never argue again and where you will never return. You never know how the next story in your life will end, but while it lasts, appreciate every moment, every second, every moment.
