" For most of us, we have warmer feelings for the projects we worked on where everything seemed to go wrong. We remember how the group stayed at work until 3 a.m., ate cold pizza and barely made the deadline. Those are the experiences we remember as some of our best days at work. It was not because of the hardship, per se, but because the hardship was shared. It is not the work we remember with fondness, but the camaraderie, how the group came together to get things done. And the reason is, once again, natural. In an effort to get us to help one another during times of struggle, our bodies release oxytocin. In other words, when we share the hardship, we biologically grow closer. "
