Working from home is not for everyone. It can be productive for certain kinds of work but not for all. Examples of jobs that can fit into a work from home schedule are those that involve research and report writing. Accounting work is another such job. If your work involves hiring people or doing marketing work, it might not be possible.
A work from home business also requires a certain mindset. It can be isolating as you will be working on your own most of the time and that is not normal for most people. It also requires a lot of independence and discipline. You are your own boss and you cannot depend on others to guide you in what you are doing. You will have to be a jack of all trade, knowing a little of everything.
