Want to be happier at work today? A brilliant person named Anonymous once said, "Attitude determines altitude." In today's workplace environment, it's more important than ever to stay positive. (Psst! Can’t get hired? Watch this free tutorial.) We work in offices without walls and doors. We send and receive dozens, sometimes hundreds, of quick messages all day. Everyone knows everything about our work patterns, schedule, and mood. We are literally working in a workplace without boundaries, and we need to do everything we can to maintain the veneer of civility. Feeling genuinely happy helps. Bosses and co-workers can read our feelings like an open book, so it's helpful to do what we can to project a positive outlook. Being happy on the job improves our reputation. Optimism makes us more resilient, able to adapt to new situations, and even more capable of solving problems faster. Happy employees receive better feedback from bosses and peers and enjoy more job satisfaction because work doesn't feel boring, difficult, or unpleasant.
