Chibiusa: "You see. Girls don't have to wait for a prince on a white horse all the time, do they? Sometimes they should ride on the back of a white horse to find their prince by themselves! It depends on whether you can make your dream happen."
(SMSS 128. Chibiusa is giving some very mature advice to Unazuki and Usagi. It's good advice.)
Fish Eye: "Hey, have you ever thought it was embarrassing to jump around in such a short skirt?"
Sailor Moon: *to chibimoon* "Have you?"
Sailor Chibimoon: "Not really."
Sailor Moon: "Yeah, not at all!"
Fish Eye: "Oh, I see. Stupid of me to ask."
(SMSS 140. Fish Eye asks Sailor Moon and Sailor Chibimoon an obvious question that oddly enough hasn't been asked before.)
Ami: "I don't think love is something to hurry yourself into. If your partner is decided by god with the red string of fate, then there will be a time for you to meet him. And I think you feel something special when you meet someone of that sort."
(SMSS 144. A simple view on love, though I mostly just find the "red string of fate" belief charming.)
Sailor Mars: "Nothing good comes out of mimicking other people! What important is being yourself! All girls have the power to make their dreams come true. What's important is wanting to do it!"
(SMSS 152. Nice advice that Sailor Mars gives to a girl named Nanako {who looks up to Rei and wants to be just like her} while she is fighting to get Nanako's dream mirror back from the enemy.)
