It's the only non-renewable base resource that we have. Everything else can come and go, but time will always be a fuse that never stops burning.
That might sound depressing to some of you, but it's motivating to me. We have a very finite amount of time left here, and it's up to us to spend it how we see fit.
Instead of looking at time as something precious that slips through our hands, try looking at it as a briefcase filled with one billion dollars. You get to spend it however you want! The absolute worst thing any of us could do is hold on to that money in that briefcase. Let's put it to work, invest it, have some fun with it, and maybe give some of it to others that only have a buck or two.
