I became the most powerful in an apocalypse

"No one trusts me because they say I am weak, I have hope that in the future I am going to be very powerful, and all those people who despised me are going to regret it because I am going to be so famous and powerful that they are going to want to brag that they knew me since they were nobody maybe that is true but I will never forgive them for having despised me. My name is Jon Stone, September 15th is my 16th birthday, you could say it's going to be my best time since technically it could change my whole life.
