You already know that most in the freelance fields can work from home, or have a virtual office anywhere that they go. The two most common of these careers are writing and photography, though freelance illustrators are also numerous. You don’t have to have one of these careers to work from home, however, as there are some great types of telecommuting employment opportunities out there, and some can be found where you already work whether you realize it or not.
You can try to look for telecommuting employment when looking for a new job, but the reality is that most of these come within your current employment. Not everyone can work from home, as some jobs require a person to be in the office.
