I met June Dershewitz at the last S-F eMetrics during a very fun kite flying session with Jim Sterne, Joseph Carrabis and Andrea Hadley.
A few days before eMetrics D.C., June contacted me to ask for permission to use one of my posts in her presentation about Career Management Strategies for Web Analytics Professionals. I think June is a proponent of career stability and she said to be very happy with her current career. That's one of the message conveyed in her presentation: you don't have to hop around, you can also grow from within. At the same time, I told her I was going freelance and she wanted to know more about it. The aspect of freelancing is also in her presentation.
You should have a look at her presentation and do a quick introspection: this will help you make sure you are in control of your own career.
