Yes. Too often, people stay at their jobs, simply because they don't even think about it. Leaving your job requires you to step outside of your routine and do something you don't regularly do. Conversely, staying your job simply requires you to stick to the same routine that you've been doing for years and years.

Don't allow your major life decisions to be made on auto-pilot. If you want to stay, then make a conscious decision and stay. If you haven't made such a conscious decision in years, it's time you had that conversation with yourself.
