Two extremes of a job

"There are two extremes of a job… the best possible thing about your job as opposed to the worst possible thing about your job. The best possible thing is that you love your job with every fiber of your being, you think about it day and night, you live it every moment, you see it as your life’s mission, it consumes every ounce of your passion. (…) And what’s the worst possible thing about a job you have? Strangely enough… it could be the very same thing."-- Don Rosa
