NEW YORK -- From his early days with East Stirlingshire to almost 27 years at Manchester United, Sir Alex Ferguson had an unparalleled career as a manager with a single-minded approach to success.
Since retiring in 2013, Ferguson's areas of focus have broadened, as he explained to ESPN FC in an exclusive interview while he visited the United States to promote his new book, "Leading."
This interview has been edited for brevity and clarity.
How easy was it to go from being Manchester United manager to retirement?
I looked forward to retiring because most people have to retire at an age, whereas I chose the time to retire, and there's a massive difference.
