It is necessary to ask ourselves first the kind of business we want to operate. It will be useless to run a business beyond your expertise or have no feeling about that business. Regardless of the profession we have, there is really a business that suits us. Of course, if you are a lawyer, your business is operating a law firm and if you are a teacher, to run a small school, and if you are an IT you may like a tech shop. There is no guaranteed business and no guaranteed job, but why should we not try to measure ourselves if able to operate a business that suits us? What do you think?
