Try tracking every penny you spend in a week. Seeing where your money is really going can help you to refocus your spending towards the things you really want. Getting paid is only one small part of what you do, your work has to be more than just a paycheck to be fulfilling. This may require you to think big, but it can be done. Take some time to really think about what you do.
Perspective plays a huge role in personal satisfaction and sense of well being.
Try to remember why you took the job in the first place. If you can't find the part of your job that you like, or if you can see yourself turning into the person you said you would never be, consider the reasons. It may not be a new job that you need, just a new direction. Maybe all that's needed is some refocusing. As much as you can choose the things you spend your time on, don't attend events or meetings only because everyone expects it.
