In the same way that we aren't given a human operating manual to make sense of life, or a parenting manual at the birth of our kids, in our careers most of us are not blessed with a manager's quick start manual as we transition to a leadership role.
Gary Winters, in What Your Boss Never Told You, bridges this knowledge and experience gap with poignant anecdotes, razor sharp insights and actionable ways to jump start your career as well as that of your team, when leadership and management become mission critical. It includes just about everything you wanted to know but didn't know how to ask with respect to getting started in management and includes some timeless gems for the seasoned manager as well.
I wish somebody had shared these insights with me early in my career! This will be required reading for those I have the privilege and responsibility to mentor on the road ahead.
