My hope for you is that by the time we finish this talk, you will know how to be well-known in your online industry circles, perfectly Google-able, and established on many social networking sites as an "old timer". You will be thought of as a valuable commodity. You will be full of confidence, well connected, and well thought of. YOU will have a strong personal brand. And your job search and work life will be better off because of it.
What makes you unique can be difficult to articulate. I recommend asking your friends, think of what you’re most proud of, think of what you’re known FOR.
