It haunts us, we are scared of it. But we spend a lot of time thinking about it. We walk around wanting it. It drives us, makes us passionate. Ditch everything we know just to chase it. Wake up the next morning hoping to revisit.
It is different for each person, and we try to make the most of it. Next year we make a bunch of promises, and swear to it. No more this, no more that, but more of it. Finally be the person we want to be, get really fit. Time passes by, we forget it. Maybe next year we will regret it.
Once you look around, you will remember it. Slow things down, take a glance, it will hit. Every second counts, do not ever quit. You only get it once, before you split.
