Cofounder of @fomo, Se Yong Park breaks down the brutal grind of building a startup "The team is locked in....I'll leave the office at 8:00 PM for dinner, come back, and everybody's still here." "There’s never been a more exciting time to grind....you get one shot to become one of the biggest companies in the world, so when you have it in front of you, you want to do everything in your willpower to make sure that happens." "We feel like we’re in this 21-mile stretch where we are going to work harder than everybody else. We are going to ship, we are going to be focused....It’s going to be painful, but it becomes less and less painful over time, and you learn to deal with it." "As a founder, you have to break new walls, go through bigger hurdles, and make sure you inspire your team to do the same."
