A recent study of British workers showed that job satisfaction was the second most important predictor of overall life satisfaction. This is no big surprise. If you’re unhappy, your job is one of the first places you should look. Your work life inevitably seeps into your personal life, and if you’re feeling dissatisfied, perhaps a career change will give you something new to focus your energies on. There are a number of things at your job that could be leaving you unhappy such as the pressure, the long hours, your colleagues or the tedious work. If you’re not happy in your work environment and it is affecting you on a personal level, it might be time for a change.
