Something Is Always Missing

There'll always be something missing,

Something left to do,

Something more to achieve,

A lot more to travel,

A lot more to do, say, plan, execute,

It'll never be enough, ever,

Which is why there's a tomorrow,

And another chance to do what you love,

But I hope you don't delay your happiness,

Because there's always a tomorrow,

It doesn't work that way then,

Then there's always less time,

And there'll always be something missing.

That's how it is, isn't it?
