Don Corleone isn't impressive because he's responsible for murders, extortion, or breaking any law that gets in his way – he's impressive because he can manage an entire organization without seeming overwhelmed.

The Godfather reminds us of the importance of being tough when necessary. “As soon as Vito Corleone allowed a few moments of weakness to be seen by his enemy, they attempted to assassinate him.

But the lesson is this–to be successful in business you have to be tough, and you have to be extremely focused on hitting goals and getting results,” says Moore.

Other helpful tips we can learn from Don Corleone include keeping yourself non-emotional about decisions or results, making sure you're decisive and stick by your decision, and keeping business and family in perspective of eachother. While nobody should really make an effort to start up a crime syndicate like the Corleone family, they can learn a few lessons from the patient, planning, and decisive Don.
