7. Never show fear of change or conflict. Embrace it.

Don's unwavering calm, only rarely broken by unexpected bouts of fury, knows no bounds. Current events that are earth-shattering for others barely register on Don's richter scale. JFK's shooting, Marilyn Monroe's suicide—it all seems to be taken in stride. Don engages in some personal mulling over the subject (see last slide), but there is no wild display of emotion. We get the sense that Don could leave it all behind and somehow be left essentially unharmed and undettered. 

When presented with a creative problem (how to make a wheel sexy?), he squints his eyes, takes a long slow slip of something strong, and comes up with the answer he needs (a carousel, duh). We rarely see a hint of apprehension enter onto his face, which is why "The Suitcase" episode, where Don cries to Peggy, was so mindblowing.

Is this the same man who pursues women with dogged persistence, but seems to take their eventual departure in stride? We almost get the sense that if we asked him their names, he wouldn't recall them. When Betty asks about Bobbi Barrett and Don denies it, we get the sense that he almost believes his own lies. "I slept with her?" he seems to inquire of himself.

Don's most impressive quality is his ability to erase the past and move forward, unencumbered.  When you're in the face of conflct, take the advice Don gives to a shock-stricken Peggy in the hospital: "This never happened. It will shock you how much it never happened." People will be in awe of you, trust.
