Since we spend so much of our time at work, it is where we forge large parts of our identity. The idea that you can separate your identity between how you act at work and how you act at home is ridiculous. The way you learn to handle yourself at work becomes who you are. This is why it is so important to do work that challenges you to be a better person and provides opportunity to grow into the person you want to be. Unfortunately many people allow negativity to consume them through most of their working life, which becomes deeply ingrained in their personality.
