About my heart - not mine

My heart is like a singing bird,
Who fly so fast,
For any one to listen its full song.
My heart is like an apple tree,
Which is so high,
For any one to have its red, thick fruits.
My heart is like a rainbow,
Which with all its colors,
Hide its true colors from everyone.
My heart is beautiful.
But for it to be glad,
Someone should swing to rhythm of bird's song,
Someone should have tree's fruits,
Someone should see the rainbow's true color.
But important is who does it or someone does it?
