Nothing ventured, nothing gained

Ten years ago, when I was at school, I had a classmate called Lucia. <Could also be phrased- Ten years ago, I had a classmate at school called Lucia> We didn't get along well. sShe was very loud and I'd just try to ignore her.
One day, my class went out to visit a museum. I was sitting with my best friend Joel, and Lucia was doingbeing loud like as always. The teacher, for a some strange reason, sat her next to me.
I was so uncomfortable. I didn't know if I should ignore her all trip or try to become friends gain her friendship. So that, I decided to start a conversation and bit by bit, I was gaining her trust. and Surprisingly in by the final of the travel, we were already friends.
Nowadays, Lucia is my girlfriend and I consider her "the best girl of the world". That's why one of my favourite sayings is "nothing adventured, nothing gained." In my case, I gained a lot.
