Do or Die time

Charlene Li, who announced today she's leaving Forrester Resarch, says:

I was once asked what was the best career advice I ever received -- and it was to plan for job obsolescence every 18 months, because research showed that people typically master a job in that time period and fall into a routine.
Based on that I'm like a way overdue library book hiding under the old magazines. But, yeah, I have a new title, a redefined role, a new place to sit, and I'm into FACTS.

Ask me in 18 months if I have it down to a routine.
