Being a pessimist won’t protect you from falling. Whether you are optimistic or pessimistic, there are times that you will fail. The difference is how you use those failures. Are you going to sulk and say you knew it would happen? Or will you jump up and try again learning for it?
Doubt
A common reason for displaying a pessimistic outlook at work is from doubting your ability. It makes sense if you say you can’t do something and then you don’t, it will be less disappointing. That is not true! All you are doing is setting yourself up. Visualizing success will bring more success. Stop doubting and have more faith in yourself, and you will see your attitude change.
Unhappy
Is your pessimistic attitude coming from being unhappy at work? Hating what you do will have a significant effect on your mood at work and at home. If this is the case, you need to see what you can change. Find those things you enjoy at work and try to magnify them. In extreme cases finding a career, you enjoy more might be the best solution.
Bored
Being bored at work can make the day feel like it is dragging on. Try taking on different tasks, branch out, and challenge yourself. Look for opportunities. Don’t wait for them to be assigned. It will be impossible to be bored if you are continually working on goals, and an optimistic outlook will follow.
