Time is like a freight train, rolling downhill.

Day after day, the train picks up speed. 

Tomorrow becomes today, faster and faster, each day feeling shorter than the last.

It feels that way because it’s true: each day is shorter than the last.

When you’re born, your first day is 100% of your life. 1/1. Your second day, it’s half. 1/2. Your third, 33%. 1/3. And so on.

Each day is a smaller fraction of your life, mathematically.

And therefore, each hour is shorter than the last. And each minute. And each moment.

I often wonder, when thinking about the past, why I say to myself: “That seems like so long ago.” And then other times, it’s: “It seems like that was just yesterday!”

It’s because of time’s fraction – always in motion.

Time: life’s constant fraction, with an always-growing denominator.

And that’s why we have to appreciate our time. 

We have to grab each day’s fraction with vigor, knowing tomorrow will be shorter.

That’s the way it goes on life’s freight train of time, always rolling downhill.
