I work from home, yet people assume since I work from home I don't really work. Boy is that wrong. In fact, I work MORE than if I had a job outside of my home. Why?
When you work from home you have to balance home stuff (chores, distractions, etc.), children (in my case there are two), and work. Also, clients don't pay you as much when you work at home because they don't have to compensate you for things like travel time, work clothes, gas, etc.
