I suggest each of the girls enter the goals they've achieved in the online Personal Progress Book. You have the option to journal your thoughts there, but don't have to write comments online. The reason I would suggest tracking goals is because sometimes books get lost of ruined, so the goals are sometimes gone forever. If they are entered online, you will ALWAYS have a record of them. It is also helpful to track your progress easily.
