Time Not Enough

How many seconds are in a day?
Quite a bit, I'd have to say.
But one things for certain, and it's tough:
No matter how many seconds, there just aren't enough!

I could spend the whole day just staring at you
And when the sun descended, I'd probably feel blue.
But thankfully, I can turn on a light
And stare lovingly at you even through the night.

The time, it ticks, and at times it's a curse
With each little tock, it grows worse and worse,
As I have one less second with which to spend
With you until my very end.

We have a limited amount of time on this globe,
And I dread to flicker out like the wane of a strobe.
Though, I've found a way with the clock to best it!
Instead of spending time, I choose to invest it.
