How to Divide 100%

Ever outpouring do I make my heart,
But that's because I want to be like you.
I know it hurts when I deny myself,
But deny yourself you do too.

I think what we need is a balance,
Where I live a little more for me,
And you live a little more for you
And then, maybe we'll see

If 90% you is a good mix for me,
And 10% me is for you a good mix.
Maybe we can do some load balancing.
Maybe I only need 6.

But no matter how much of me I deny
For the sake of giving you your part,
You'll always have 110%
Of my lovin' heart.
