• Never tell a girl your real name.

  • Never give a girl your number, and never call her from a phone that is personally traceable to yourself.

  • Never take a girl back to your place: go to her place, spring for a hotel, whatever, but never let her know where you live.

  • Use cash.

  • Avoid relationships, falling in love, and anything remotely resembling commitment. Think of a girl as a jewel heist. Get in. Get out. Leave no evidence.
