In the big picture, the process of developing your own brand is a lot like developing a brand for a product or service. You want to start out by identifying the goals of the branding: what, exactly, do you want to achieve? Who is your audience? What do you want them to think about your brand? What associations would bring the best results? Who and what should you be affiliated with?
Once you have a goal established, the next step is to figure out where you are currently on the path of achieving that goal, followed by a series of steps intended to bring you closer to that goal.
