You could read a million pages, know the words and all the phrases. 
You could try to turn a lie into the truth. 
You can live to be a hundred, memorizin' every number. 
You could even put a man on the moon. 
And the science of the heart is sometimes lost on me. 
But I'm following this feeling! 

I don't know why, it's so hard to swallow our pride! 
And I don't know how many wrongs make a right. 
I don't know the reason. 
Sometimes it just feels so good to cry! 
And I don't know which way the wind will blow. 
But you're here with me. 
And that's all I need to know! 

There's a moment in the morning, when I feel the most alone 
But then I hear your voice, whispering my name. 
It's like a wave of understanding and I never could have planned it 
Where the questions, and doubts all fade away. 

I don't know why, it's so hard to swallow our pride! 
And I don't know how many wrongs make a right. 
I don't know the reason. 
Sometimes it just feels so good to cry! 
And I don't know which way the wind will blow. 
But you're here with me. 
And that's all I need to know! 

That's all I need to know 

I figured it out, you turned me around at the speed of light. 
All that I ever needed to know was in your eyes. 

I don't know why, it's so hard to swallow our pride. 
And I never count all the stars in the sky. 
I don't know the reason. 
Sometimes it just feels so good to cry! 
And I don't know which way the wind will blow. 
But you're here with me. 
And that's all I need to know! 

That's all I need to know! 
That's all I need to know. 
All I need to know!
