1. Be as contradictory as possible.
"People tell you who they are, but we ignore it—because we want them to be who we want them to be." In Don's own words lie his personal brand of intrigue. Don's most detestable actions clearly tell us who he is (an insatiable womanizer driven by selfish desires), but we still want to see him as more.
Don is a lovable scoundrel only because he evades definition. We watch him baiting a flight attendant with elaborate lies just after he's warmed a glass of milk for his pregnant wife. We see him unleash of spitfire of insults on an unwilling client, and minutes later he's gently encouraging Peggy. We see him asking to be slapped by a prostitute, and just minutes later he's the warm, caring father instilling values in his children.
Don's faults are just as integral to his swag as his strengths, if not more so. His charisma is derived from this sense of conflict. He is both the bad boy and the gentleman, and he is wildly unpredictable because of this dichotomy. He is a walking enigma that begs to be dissected, and yes, humped.
Harness your own set of contradictions. Don't shy away from inconsitencies, embrace them with an unbridled panache of Don Draper. Believe you are "beautiful...interesting and modern" like Frank O'Hara insists, but balance that with the "catastrophe of [your] personality. You are not wholly good or bad. You too are a walking enigma, a nut that people will clamor to crack.
When they're scratching at your door, desperately wanting into your head, you can thank us.
