I find it annoying that people constantly watch me. If I don't smile first thing I come to work, something is said within a minute about my "mood". It really gets on my nerves and makes me even more stressed out.
I've got a great way to deal with that: Plaster on a big cheery smile before entering workplace. Smile at each and every person you make eye contact with and say 'Hi!' Anyone asks how you are, don't just say 'fine', say 'Amazing, I'm having a great day!' Anyone whines about their job, say 'I actually like working here, you know.'
It's a funny trick to pull on yourself, because even if you're feeling a bit teed off about stuff, acting happy and smiling actually releases endorphins. It's been proven. By real scientists. So if you can get into the habit of kidding yoursel fon you're happy, you actually become happy.
Everyone in my work thinks I'm unusual because I'm always in a good mood, I rarely whine about anything and I don't bitch about any of my colleagues. Secretly I disdain most of their fat lazy asses and their brain dead chat, but letting them know that wouldn't exactly be conducive to a healthy working atmosphere. So I fake it and they like me for it. Haha. I'm such a sneaky witch!
