A Failure of a Story that I'm not deleting merely for future motivation.

Rarity never gave anypony any consideration before she left. She had no reason to dabble with those miscreants that she once referred to as "friends", so she prominently deserted them and instead pursued her own personal career within the fashion industry.

It was clear to anypony that Rarity was definitely a talented pony. Her dress handiwork was astonishingly detailed and well recognised, even when she was only a growing prospect in the small town of Ponyville. All that was necessary was that one trigger, that successful break, that slight gain in popularity and she would be propelled up into the limelight. Such a thing happened to Rarity, which led to her immediately departing from her previous life.

Word slipped into Canterlot about Rarity and her magnificent dresses. One by one, ponies began to purchase Rarity dresses and flaunt them off to all of Canterlot: which only caused more ponies to become intrigued by the Carousel Boutique and what it had to offer.

It wasn't long until Rarity had hit the top: she was a huge hit with everypony in all of Equestria.

Subsequently, Rarity left everything she had behind her and instead chased after her dream, being popular in Canterlot. She opened up a boutique there; it wasn't long before customers were rolling in, queuing for miles just to wear her apparel.

Nowadays, Rarity couldn't have cared less about her old friends. In fact, she didn't even remember them or remember a time before she was huge in Canterlot - her success had not died down since her break.

Although Rarity had definitely deserted her "Generosity" element a while back, she was insatiably happy with her life. It wouldn't take a clever a pony to tell you that she had no interest in getting her hooves dirty with such petty things as 'saving the world'.
