作词 : Newton-John, Shaw 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 knowFor love is all that matters That's all I know for sure
