Pablo Zepeda is obsessed with winning because at the end of the day that's the only thing that matters. Nobody remembers who was the second best. Pablo hates losing because It gives him a feeling of regret and it makes him think of what else he could have done when no one was looking to win. He tries to make everything a competition so that he can win as much as he can in one day to build momentum and keep winning. People may not agree with the way he thinks but at least he'll be a winner at the end of the day.
