The Wall Street Journal runs a regular section, "Career Journal" — nowadays often focused on career transition, and getting started in your new life.

"You Just Have to Do It," by regular Alexandra Levit, points out that "people in the midst of a career reinvention 

don't have the luxury of a manager who sets priorities for them."  Luxury, or blessing depends on your point of view: on how tired you are of "being managed," and on ready you are to be a self-starter.

The article cites David Allen's, Getting Things Done: The Art of Stress-Free Productivity, a new classic.  One point: "It helps to recognize that being a self-starter is a set of behaviors that you can adopt."

A set of behaviors you can adopt— great point.  A lot of the stuff we accept as "just the way I am, no changing that," is in fact old behavior patterns that have built up over a lifetime.  Behavior patterns like "put-it-offness," "let's wait for more data, just to be sure," and "I'm going to quit watching so much TV and get started action planning my new business– next week for sure."

Enough said. Best just to go to the source:  Go to Wall Street Journal article, "You just have to do it"
