Is it time that runs out or us?

The days go faster than I think. It's like there's not enough time to do enough. But yet, I still find time to do what I like. We waste time on things that are not important and we blame time for not being enough. Hours turn into days, days into months, months turn into years and years turn into a lifetime. But still, we say time is going. And I ask yet again, is time really going or our time on earth is what is reducing. Time has and will always be. But that's not the case for us. We will exist for a while, and then we cease to exist with time. There is not much of us that will be available for long. So, the next time you are doing what you are not supposed to do at a time, remember this: "You are not wasting time. Rather, it is you who is wasting away."
