The gap between hobby, passion, avocation, etc. and a business is huge. One of the surest ways of curing yourself of a passion is to try to make it a business. Winning enough money in the self-owned business environment to care for your family is a difficult undertaking under the best of circumstances. Wishing to run your own business is very understandable. However, this must be done with a straight up business approach. First, you must, absolutely must, identify a need for which people will pay money. This will usually be something nobody else wants to do, not something everyone else wants to do. Then, you must realize that your job is business development, not doing whatever it is your business does. If you don't have a passion for business development, stay out of business. If you imagine that as your own boss you will have time for all the things you don't now, don't go near your own business. If you are going to succeed, the committment is 24-7-12-20; 24 hours a day seven days a week every month for the next 20 years. Family and marriage will have to take a back seat. And, you still may fail. Don't even dream of quitting your day job until you absolutely know how you can make a successful business. If you can't make your hobby make money in your spare time, you sure can't make it into a family supporting business. The realities of a self-run business are stark compared to the dream.

Mind the gap!!

If you are still having the dream, start on a business plan and start checking it with other, successful business develpment people who, hopefully, will tell you the truth about its viability. Especially listen to those who would loan you money (because unless you are already independently wealthy you will have to have capital).
