Time is the most valuable resource we have. Every second with a loved one can be precious. Every minute could potentially define us. Every hour could be spent doing something that will benefit us for the rest of our lives. Any day could be the best or last day of our lives. And unlike money water and other resources, time cannot be earned back or replaced.
The past is either time lost or time well spent. Time invested today can still benefit the future. The only question to ask is if what we're doing today is worth it?
