Be CEO of something, dress sharp, get fit. How you look, act, and dress is your UI most hackers have a really shitty UI. Get a good logo, great cards and a good website / brochures. Pay others to make these things, use fivver, put everything out to bid, some people are really cheap, don't be afraid to hire people undercharging for their services. Tip them so you get prioritized.
Sell something repeatable, anything you can pay someone else to do, pay them. Get a lawyer, a good accountant, create your own contracts, run any serious changes by them.
Make sure you have quotes from your subcontractors, double it. Triple it. 10x it. Charge that to your clients. The more you charge the better you are.
Basically be the fucking man. Don't apologize for it.
Read everything by Robert Cialdini. It's a hacking guide to the masses. Read how to win friends and influence people it's a guide to hacking individuals.
Realize everyone is winging it and actors are doctors when they wear lab coats, lawyers when they wear suits and bikers when they wear leather. It's not hard to pass for anything wearing the right clothes.
Don't be afraid to bill $500 for something you paid $24 for. Never tell people how much something cost you or where you sourced it from.
Be really nice and highly complimentary to people.
