Smile N Feel Positive!
Did you know that simply smiling, even when you don't feel happy, can automatically put you in a better mood?
It may seem fake at first, and I don't recommend being disingenuous, but if you feel negative often at work, don't forget to smile.
:) Smile at a passing coworker in the hall
:) Smile as you answer a customer's question
:) Smile even while you are by yourself
Yes, this can really help you have a more positive attitude at work!
This also can help other coworkers think of you as a positive and friendly person, and when those around you are in a good mood and like being around you, it is easier to get rid of any of your own negative feelings.
Smiling can not only improve your attitude, but if can actually help you be more successful, and believe it or not, some studies suggest that smiling can even help you live longer.
If that isn't a reason to smile, I don't know what is!
