That is not what this exercise is about. Just jot down some things that you really enjoy doing, and try to be as honest as possible. Try to remember times when you felt happiest, your most vibrant and alive. Once you have finished writing down the things you are most passionate about, try brainstorming about how to turn those ideas into a business. This can be a very important question, or, believe it or not, a completely irrelevant one.
Many people start their own businesses without an ounce of experience in their business field.
You may need to take classes, attend seminars, or just practice, practice, practice before you learn your trade. But the question still needs to be answered. This 'experience' need not come only from prior jobs, but also from volunteer positions, hobbies, school, etc. Once you have finished writing this down, try to see how your experience could help you turn your passions into a business. If it's that cut and dry, you have a link, and a very feasible place to start your brainstorming.
