Take a stretch job/task to sweep the career cobwebs away
One way I've learned to get myself out of the career doldrums is to take a new job or task that will require me to "stretch" myself. Many times we do not champion our career as we should and by taking on more responsibility or by requiring that we grow into a new position, new energy can be discovered and greater rewards will come, e.g. higher pay and greater job satisfaction to mention a few. All that's needed is only the desire to grow and the persistence to making it happen.
