Chicken noodle soup...

As I sit at work, eating homemade chicken noodle soup. I wonder why on Earth I would come back to this hell hole of a job. When I was younger I never expected to grow up to be a cashier. I never knew what I wanted to be. My mind was always changing. One day I wanted to be a teacher, the next a vet, and the list continues. As an adult my list does not seem so limitless. The job I have now is essentially the same one I have had since high school. I am in a comfort zone and the thought of leaving it for bigger and better things, well, it scares the crap out of me. What if its not a better job? What if the people I work with are just rude? The what ifs in life become overwhelming and in the end scare me into submission. I want to know at what point I became such a chicken? Never taking that leap of faith that may be what makes me happy.
