There's nothing wrong with working the same job everyday. However, this doesn't work for everyone. Some people weren't made for a day in and day out routine. If this is you, a career in market research might be well suited for you.
A market researcher runs surveys for a variety of different companies. Market researchers can work by themselves or through a survey company. If you are on your own you can make your own hours, but you won't get paid health benefits or additional benefits that would come with working in-house.
