Answer 1

Hola,
No entiendo bien tu pregunta, pero creo que consiste en ordenar la secuencia lógicamente.

At the age of 16, before he was an adult, he wanted to start working. 
But, after he began to work as a waiter in the year 2012, he realized that work it's too bore when he started to lose his social life because his work schedule. In that time, he eventually used to miss his friends and that's the principal reason why he finally left his job. This was a recently new. Currently, he is just studying and living his teenage life; always meeting with his friends.
