except the fact that you forget she had no intention of being Celestia’s student.
 
The enrollment of the school was a gift from her parents in their way to support her passion for magic. It was all just dumb luck that she managed to not only get in but have Princess Celestia herself teach her personally. She never intended to be a princess, she was just thrown on the road to become one. She didn’t specifically want to be more like Celestia, just be able to use magic like her.

Starswirl built upon the actions of prior unicorns too.
 
And Twilight was training to become a Princess. Look back to Cutie Mark Chronicles. What was it she wanted, and why? From the beginning, she wanted to be like Celestia. It would take some time for her to become socialized enough to realize it, rather than think of it as “becoming great at magic.”

@Lester  
I think its more commendable that Starswirl even made it that far with the spell regardless of the fact that there was one of two options in his time frame.
 
He was either alive when the Elements of Harmony were still one spirit or he was alive when the Elements of Harmony didn’t exist anymore. Yet he managed to make a spell that affected them when they separated into 6 different spirits. The only reason he abandoned the spell was because it was literally impossible for him to perfect it because it had absolutely no visible effect due to the fact that he didn’t have access to the Elements of Harmony.
 
Also, it was one spell, and it was something she fixed. Starswirl actually researched and created new spells. Several, as implied by the show.

@Sonar  
I don’t think Twi actually studied in the standard classroom setting as she was personally studying under Princess Celestia. Besides, the fact that she completed something that someone failed to do so in the first place should be commendable.

EVERY leader should be done the second way.

And save equestria and rewrite a spell the most powerful mage in the history of Equrestria was not able to complete in just a day.

Waiting for the fucker who will vote this down.

Son,I’ve got some news.

@Bobrella  
That’s not really how it works in any monarchy I’ve heard of.

@WassonG  
Like a certain Princess Mononoke?

More like:  

OP forgot the most important one: Conquering a Principality.
 
You know, the way Celestia and Luna did it.

I prefer my princesses raised by wolves.
 
however twilight’s ephemeral stroll through the ether with her mentor is pretty cool too.

@Trickquestion  
“Don’t you mean Shining?”  
“Sssh, you want to get sued?”

Wasn’t Cadance born a princess?

…huh. I never thought about that.
 
Maybe this isn’t such a bad thing.

no inbreeding at least

She was already a Princess technically, her brother became a Prince after marrying Cadance.

Equestria, duh.

I prefer if executive meddling made me a princess.

Makes sense to me. Celestia and Luna don’t seem to be planning on getting married any time soon, and they might eventually tire of their duties. Then who are they going to pass the throne onto? Blueblood? Meritocracy is the way to go on this one.

You forgot ‘Have being a princess be your destiny as fortold by a god’ on the list on the right

Shinning Armor’s smarter then her. While she studied and worked her flank off for power, Shinning just realized he could fuck his way into monarchy.

neither, princesses are girly
