I've never met with them.All the hype around an upcoming book by Facebook's COO on women and work, titled "Lean ln", made me wonder about the exact meaning of the phrases "Lean ln" and "Lean back".
One of the reviews includes an explanation: "The title comes from her advice ... for women to lean in to their work rather than lean back, as many tend to do for a variety of reasons at key points in their careers."
I get the general idea, but not clearly enough. Is this a metaphor? An image of someone leaning forward or backward I should have in my mind? Are these expressions with a known meaning that would be clear to native English speakers?
