This is so beautiful and sad
Although I can't say I share the same sentiment (I think my childhood self would be content with who I am now) I must say I love the music and how simple it is, almost child like.
Oh and I love the ending I think the change kept it perfect, I wouldn't have changed anything the bells keep an innocent feel.
I suppose we lose our innocence, it that sadness that makes this piece so moving. The thought that our younger selves aspire with such purity and ignorance at the world that our older selves break when we wonder how we have changed.
It's beautiful and retrospective almost nostalgic.
The sentiment is nice, even though I can't share it. (I've never really had dreams so I never needed to fulfill them)
