After reading a few of these articles I will say that there is no hard and fast formula for being able to start a business and it appears that most readers prefer to have a how to approach as if there were someone there to take your hand and guide you through. That would be a step that you would have to take by taking an evening course at a local college or university or by taking up an initiative and open up a co-op with a friend as a step towards being a sole-proprietor of a company.
Firstly, starting is not a thing to do for the wavering personalities and the weak of heart, you have to be prepared to work long hours, change your time schedule and work with other people not to mention work out a business plan if you want to be able to budget carefully. A lot of people work spontaneously without sitting down and doing a plan in hard copy. That might be good for very small businesses where there is little or no spending, like freelance teaching. In the long run, having a plan will help the entrepreneur know how much money he has available and how much he can invest into other projects.
One has to think of working from home or at an office space. Today is quite an advantage to use your own living space and set up a desk, computer and copy machine so that you can operate from your own personal space. Again this depends on whether you are disciplined enough to set aside the necessary hours to work out of your home near the coffee machine and not get up and every other hour for a drink or a chat on the phone.
I would also speak to other people in your discipline to ask how they coped with working form home for new ideas and on how to save and improvise.
