It can be short

It can be long

I can be right

It can be wrong

It can be good

It can be bad

It can be all that one had

It can be saved

It can be wasted

It can be lost

It can be found

It can be new

It can be old

It can be something that is told

It can be borrowed

It can be spent

I can be fast

It can be slow

It can be down

It can be up

But it cannot be replaced nor will it stop

So my advice would be

Use it, but use it wisely . . . time!
