Belle had reading and housework and her father keeping her busy while she waited and watched for her Prince in disguise. Also, Belle didn't take her father's place in the tower to make the Beast fall in love with her and become a princess. She did so to save her father from certain death, selflessly and lovingly.
Ariel didn't become a human to find and woo a human prince, she did it to try something new!
Snow White wasn't singing while she worked to have her voice win over her prince. She did it to make her work more bearable.
Sleeping Beauty didn't dream so that Phillip would one day appear in reality. She dreamt to feed her active imagination and hopes.
Jasmine didn't go out in the marketplace to find Aladdin and make him a prince. She went into the marketplace to escape her life that she'd grown unhappy with and find her own place in the world.
Tianna didn't kiss Naveen to go on a grand adventure and become a princess. She kissed him to help him out. She also worked hard to get what she wanted in the end.
Rapunzel didn't leave her tower to fall for Flynn (or Eugene, whichever you prefer to call him). She left the tower to have an adventure and to discover what the lights were, not to mention to spite her "mother".
What I'm trying to say is: don't just sit there and wait for Prince Charming. Do something: read, paint, try something new, escape, dream, sing, help, whatever it is that helps you be you. In time someone will come along and sweep you off your feet and carry you off to your dreams. And if you've already been swept off your feet, count yourself lucky.
"Some day my prince will come, some day I'll find the one. Though he's far away I'll find my love someday, someday when my dreams come true!"
