Among the secret backroom bookshelves of anxious beta-males you will find well-thumbed rulebooks on the keys to success, power, and confidence.

Squeezed alongside "The Art Of The Deal" and the creepy teenage boys’ pickup artist manifesto that is "The Game", you’ll discover tomes about strength and influence that focus on the sorts of trivia over which only anxious losers would fixate.

Chief among the details that these books contain will be advice about wearing powerfully coloured ties, and reminders to possess a firm handshake.
