I became a brony on the 30th day of October, back in 2011.
This particular Sunday, I was bored doing my homeworks. So I decided to take a look at this cartoon because I liked its design a lot.
I began watching the 1st episode at noon but stopped just after the opening. I really wasn't convinced by this opening and I first thinked "What am I watching? It looks really childish!".
Buuuut... the sequence with the book just had triggered my curiosity. Besides, this lavender unicorn, she seemed so geeky, I wanted to know what she was going to do with this legend!
So I watched the episode completely before going to sleep. And I enjoyed it more than I thought at the time!
And then I became a brony. I enjoyed the forums, the fanfics (My Little Dashie was a punch in the face so much! ), the Equestria Daily, and, of course, the episodes. I spent nearly 2 hours per day reading articles and fanfics at the time.
These were good times. I regret nothing. And it continues.
