Different people have different reasons for wanting to work from home. My personal reasons are so that I can be home and return to my favorite lifestyle - that of a stay at home mom, even though my kids are grown. The stress and pressure of working outside my home and the lack of time here to really do the things I love are my driving force.
Others have other reasons for wanting to work from home, though. Maybe they want to be able to raise and homeschool their children while they generate some extra income. Maybe there are health issues that prevent them from working an outside job. Things like severe arthritis, fibromyalgia, or injuries can make an outside job impossible. Or maybe they just like the idea of being their own boss and setting their own hours for work, being in control of their own destiny.
I'd love to know your reasons for wanting to work from home!
