เนื้อเพลง That's All I Know for Sure - Olivia Newton-John

This life is so uncertain
That's All I Know for Sure
You spend your whole life searching
Thinking there's something more

And I wish that I could paint you skies
With brightest moons, with sun forevermore
But rain could fall tomorrow
That's all I know for sure

I don't regret a moment
That's just a waste of time
When tears apart have growing
I've had my share to mind

And time has a way of healing pain
We only gain from learning to endure
Life has no rhyme or reason
That's all I know for sure

If I can give you anything
To make you stronger than you are
Is that the key to everything
Is right there in your heart
Right there in your heart

For love is all that matters
That's all I know, that's all I know
For love is all that matters
That's all I know for sure
