The answer is in your wording: 'I have a great and interesting job. I am generally successful'. That sounds like a pretty good going, so why change it by needing to be great? It's not your fault that you don't care enough, it is your current circumstance. Often, greatness comes out of intense desire to change one's situation, more as a byproduct. You could try to simulate that intense desire by imagining dire situations, such as losing your job next week, or as buddhists do, intensely visualize pain, suffering and death to help others (Tibetan buddhism).
