The best business for anyone is going to be the one in which you are most skilled and interested, and have some previous experience and there is need that you can fill well, if not better than anyone else. Most important, do what you love and the passion and interest will help the money to follow. You need to research the growth potential of various businesses. Matching your background with the local market will increase your chance of success. You can gain confidence and be realistic about your specific business idea if you can test it as something that is timely and appropriate (for the economy and your industry); is right for you (your personality and skills); matches your level of commitment (motivation and interest) and is clear and concise for others to others (easy to understand)
