Stick to basics. It's okay to work in your underwear in your partially remodeled basement as long as everyone thinks you're in a suit in a high-rise on Success Avenue. It's NOT okay to broadcast your slovenly habits to the world at large via ill-formatted email, poor spelling, sloppy grammar and inept punctuation. If every second line of your email breaks after the first word, we're done. Caps in excess.
Exclamation points in excess.
Hyperbole in excess. It's a hot dog, not the second coming. The Internet is still real life. Set up an honest business, cook a decent hot dog, pay for advertising and don't quit your day job. Get rich slowly.
