In the first year of my full time employment, I walked into the office with a big smile on my face everyday and greeted everyone I walked past with a “Good morning!”. It wasn’t until I got assigned a really big, difficult project loaded with difficult client & office politics that I would have headache every morning. I felt my energy level steadily decreasing as soon as I left home, and drained completely when I walked into the office, resulting in a grumpy face and my morning greetings dissapeared. I was agitated and impatient all the time, and I had difficulties sleeping. When I woke up, it felt like I hadn’t slept at all. Pretty soon my health started falling and I had to take an unpaid leave to recover.
