The idea has to be something you’d devote your life to. This will help ensure success no matter what comes your way. The idea can be a process, a process is also a service. The important thing is not to limit yourself. Once you have your idea, build a model and begin conducting business. Define your limits through fair sound business practice. When you listen to the back beat of a Beatles song, its on the quarter note, so it stands. If sound business practice is the back beat of your company it’ll stand.
