As Crawford and Czuczka write: "... Merkel consults widely to better formulate her approach to policy making. She is not given to snap, intuitive decisions, but is rather very deliberate in the way she reaches her conclusions."
But what also makes Merkel most unusual is how little her lifestyle has changed since assuming power. In contrast to fellow politicians, she lives a modest way of life residing in her Berlin apartment with her second husband Joachim Sauerspends.
What's more, she doesn't put on lavish displays when hosting world leaders and she continues to spend weekends away from public glare at her home in the rural hamlet of Hohenwalde, east of Berlin.
Though she is often described as "boring" and has been known to give long press conferences without revealing anything of news value, her understated political persona is her strength.
In an age where pomp and performance can seem to trump policy and substance, Merkel is the exception to the rule. Her shrewd negotiation skills and ability to deliver make up for what she lacks in charm and charisma. After all, sometimes the ability for a leader to govern is more important than the ability to warm a crowd.
