It was a beautiful day in Equestria. A quarry opened, and all the ponies that worked there were stallions. They would collect stone, to make statues, buildings, sidewalks, and many other things.

One day, Rainbow Dash met with Celestia at her cloudhouse.

Celestia: The quarry needs a pegasus to help out for a few days. The manager, and I agreed that you would be the best option. I will find others to take over your work until you get back.
Rainbow Dash: I won't let you down. *Flies to the quarry*

By the time she arrived, Rainbow Dash met an earth pony named Michael. He was not happy to meet Rainbow Dash

Michael: Oh, I've seen you around town before. What are you doing here?
Rainbow Dash: Princess Celestia sent me here to help.
Michael: Well we do need a pegasus, but a mare like you can't get the job done.
Rainbow Dash: That's not true. *Goes to start work*
Manager: *Hiding in a shadow, so you can't see what he looks like* Hey kid, forget about Michael, he was once called Douchebag, but he somehow changed his identity.
Rainbow Dash: Isn't that illegal?
Manager: Not unless you pay the government. Listen, all I need you to do is fly towards part of the cliffs, and kick some rocks down. When they hit the ground, other ponies will collect them. You'll be staying with us for a few days, so we made a place for you to sleep. One of the workers will show you how to get there.
Rainbow Dash: Thanks a lot. *Flies up towards cliff*

The rocks weren't difficult to knock down. At the top of the cliff however, Michael was making plans to sabotage her work.

Rainbow Dash: *Kicks rock down to ground*
Worker: *Picks up rock, and puts it in wagon*
Worker 2: *Pulls wagon*
Worker: Thanks Dash. Keep up the good work.
Rainbow Dash: You got it.
Michael: *Has a big bucket of sand* Hehehehe! This will be great!! *Runs down cliff*

Nearby, was a swing. It was being held back by a rope, but Michael was going to shoot the rope in order to make the swing hit the bucket, and pour the sand on top of Rainbow Dash.

Michael: Nopony can see me. Hahaha! *Aiming gun at rope*
Rainbow Dash: *Kicks two rocks towards the ground at the same time*
Michael: *Shoots rope*
Worker: There's sand falling from the top of the cliff!
Rainbow Dash: What? *Looks at sand* Oh boy! *Gets hit by sand, and falls on ground, then gets stuck*
Michael: Hahaha! *Walks over to Rainbow Dash* What were you thinking? Just standing there, and letting the sand trap you like that? You're such a wimp.
Rainbow Dash: You caused that on purpose!
Michael: You can't get out, can you?
Rainbow Dash: No!
Michael: If you can't get out of that pile of sand, you probably don't have what it takes to pull a wagon with a heavy load. No wonder why mares get killed in favor of stallions.
Rainbow Dash: I don't believe you!

Later that night, Rainbow Dash was thinking about all the sexist things Michael said to her, and she was worried. Maybe he was right. What if all mares got killed in favor of stallions?

Next morning, she was still feeling sad. Big Macintosh brought some apple cider for the workers.

Michael: Awesome, you're the best Big Mac.
Big Macintosh: Eeyup.
Worker: Cider time!
Rainbow Dash: *Goes to get cider*
Michael: Not you! This is for stallions only.
Rainbow Dash: But I want some!
Michael: Too bad! *Drinks cider* Aw man. This is good.
Worker: *Drinks cider* You'r absolutely right. This is delicious.
Michael: I'm going to collect a lot of rocks for everypony now. *Runs to get started with his work, then falls on ground, and coughs* I don't feel so good!
Worker: *Coughing* Neither do I!
Big Macintosh: *Looks at cider* Oh no! This cider expired.

All the workers were not feeling well. The only ponies in the quarry that didn't drink the cider were Rainbow Dash, Big Macintosh, and the manager.

Manager: *Still hiding in shadow* Can any of you get some medicine to cure these ponies? The pharmacy is a mile away, and we need Code X vitamins to help everypony feel better.
Big Macintosh: I have to go back to Sweet Apples Acres. Later. *Runs away*
Rainbow Dash: I guess it's up to me.
Manager: Yeah. Don't let us down.
Rainbow Dash: I'll be back with the medicine. *Flies to pharmacy*

When she got there, she wasted no time asking for the medicine.

Rainbow Dash: I need all of your Code X vitamins. This is an emergency!
Doctor: I'll get it set for you quickly. That'll be 500 bits.
Rainbow Dash: *Pays doctor 500 bits*

Rainbow Dash was hitched up to four wagons, and they were loaded up with the Code X vitamins. All of the wagons were heavy. Rainbow Dash pulled as hard as she could. Her hooves slipped, so she tried to pull the wagons by flying.

Rainbow Dash: *Can't pull the wagons* I gotta get this to the quarry! I can't let anypony down! I, think, I, can! *Starts to pull the wagons* I'm doing it. I think I can, I think I can, I think I can, I think I can!

She continued saying those four words, and soon it was easy to get all the way to the quarry.

Meanwhile, at the quarry. Everypony was getting sicker, and sicker.

Michael: Uugh! I knew we couldn't trust that blue pegasus!
Worker: She'll be here. I know she will.
Worker 2: You shouldn't have been so mean to here Michael.
Michael: Shut up!
Rainbow Dash: *Arrives* Special delivery! Code X for everypony that is sick.
Worker: Ha! I knew it.
Michael: *Not happy*
Rainbow Dash: *Stops next to Michael, and is very tired. Much of her face is red from exhaustion, and some sweat is seen coming down from her head.*
Michael: *Stares at Rainbow Dash*
Rainbow Dash: And you thought I couldn't pull a heavy wagon. Well, I pulled four.
Michael: I don't believe you.
Rainbow Dash: I don't care. I made it here all by myself, and you thought I couldn't do it. No wonder why mares are better then stallions.

Celestia soon arrived with Pinkie Pie.

Celestia: Well done Rainbow Dash. You brought the medicine here, despite all the bad things Michael said about you.
Rainbow Dash: Thank you Princess.
Pinkie Pie: And now it's time for a party! *Shoots party cannon into sky*

The last few days working at the quarry wasn't so bad for Rainbow Dash. They threw a party for her, Michael got fired for good, and she became friends with everypony working there.

And there is a lesson to this story. Sometimes in life, the only way you can achieve something, is by thinking positive, which is what Rainbow Dash did in order to get all the heavy wagons of medicine to the quarry for everypony working there.

The End
