Fluttershy happily tended to her animals. Everything was calm, just the way she liked it. She fed Angel a carrot, who munched on it cheerfully. There was a shining look in Angel's eyes, with only a carrot. Fluttershy wished that she could be that gleeful with only a carrot. Yes, she was happy, but she wanted more. All of her friends seemed to have dreams. She was the misfit.
She was shy, and never seemed to have a place except for with the creatures she cared for.
Twilight wanted to claim her place in the world, by becoming a princess. She thought that ruling alongside Princesses Celestia, Luna, and Cadence would bring her joy. She had powerful magic too.
Rainbow Dash wanted to be a Wonderbolt. This was basically her only dream. She was loyal, which made her a good teammate. She'd even interacted with the Wonderbolts before, bringing her one step closer to being one herself.
Pinkie Pie, well, her goal was simple. Be happy!
Applejack, well, she wanted to support the rest of the apple family, and have the apple sales high. Good feedback was important to her.
Rarity just wanted true love. It didn't work out between her and Prince Blueblood, so she was on a quest for true love. In the meantime, she created fashion trends.
It wasn't that Fluttershy didn't like caring for the animals, it was just that, that, well, what was her purpose? What was her point in life? Would she find true love? Would she become a princess?
LHer future was wide open, she just didn't realize it. She would find her purpose. Let's just say, her life was about to change.
