Your attitude is the single biggest predictor in your success or failure at any job. Employees fail to realize that their attitude is a picture to the outside world. You can choose to let your problems sour your attitude; or you can turn your problems into opportunities. You can choose to complain; or you can realize the complaining solves nothing and correct the issue. You can associate with negative people that pull you down; or you can surround yourself with positive people that make you feel better about yourself. If your attitude sucks, suck it up and commit to change your attitude or remove yourself from the environment. What picture do you want the outside world seeing of you?
