This is always a toughie. A lot of jobs can become monotonous, especially if you’ve been at it a long time. My instinct is to tell you to continue looking for a job that will make you happier, but in the mean time, you’ve got to spice up your job by putting your spin on it. What I mean by that is, find a new way to do your usual tasks that is unique to you! Inject your personality into your work.
If you work in sales, think of some topics you personally enjoy to help find common ground with your customers. If you are on the computer handling a lot of spreadsheets, create a new, fun color scheme to keep things organized. If you work in an office with a strict dress code, accessorize in a way that can bring up the mood of yourself and those around you, like a funny tie or a cool pin. Who knows, you might even find that your job isn’t so bad after all, or the extra effort may get you noticed and promoted. Worst case scenario, you were brave enough to try something different.
Hope that helps! Til next time..
