I'm rather intellectual, easily swayed by good arguments, well versed in enough subjects to never run out of things to say, have stylish enough skin and hair for even the shallowest of acquaintances, and am fairly "different" and aloof enough to have an heir of exotic foreignness to me, that attracts people from any crowd. Someone will inevitably once or twice make a snarky remark about "eh, he's cool, but a kinda nerdy guy", and that's where charisma and luck come in.
And if that doesn't work, I'm a fucking Viking. Hide your women, if they're not already immediately bowing at my feet, praising the gods of victory and lust for my triumphant appearance, then I'll steal them away sooner or later anyway.
