See what others have done. See what you can do. Copy it. In general, you want to stick closely to the tested and tried and true as possible. After you are established, there will be plenty of time for you to innovate and try new ideas.
It is much easier to become successful by cloning an established business concept than by attempting to create a new business category. If your plan is to make money without drama, imitation trumps innovation. You can make your fortune selling donuts or running laundromats. However, trying to tie the two businesses together in some novel cleaners/restaurant way may be a brilliant idea or, more likely, a money eating and time consuming disaster. If no one else has ever done it before, there may be a good reason for that. Find success and copy success.
As you think about career opportunities, don’t forget any networks or connections that may give you an advantage in starting or developing your own business. Did you acquire skills working as a child in a family business? Can you take over an established family business? Does your uncle or your neighbor or your brother-in-law or a former classmate have connections to assist your business? Somebody you know probably knows somebody who would be willing to give you special assistance because of a personal contact. Build positive business networks. Associate with others committed to self-improvement and helping others. You can go far by yourself and even farther with the help of other people.
