Answer:
I think that it may be " I'll add a few new paintings to my gallery " or " Just wonder when will my life begin?”
Explanation:
Rapunzel sings this song and she does not have a gallery but only paintings
it could also be the last line because no one can really wonder when will there life begin when they are all grown up and already have a life. If they did not have a life yet they can't think yet.
Hope I was able to help. =)
