There are a few other posts about this same topic and probably a thousand other articles online with much more content. I just wanted to add three things that I noticed that are a bit more specific.
(A) Never act impressed: Always keep your composure. Even if you’re playing basketball and someone makes 15,000 shots in a row or you’re having secks with a contortionist from Cambodia and she puts her legs behind her back and starts eating herself out; don’t act bewildered. You can say “wow” or give credit where it’s due, but never act dumfounded. If a magician comes up to you in the streets and pulls a rabbit out of a condom, reply with “I’ve pulled bigger things out of a condom.” Don’t put down other people, but don’t act like a 10 year old boy who just saw a naked woman for the first time. If your girlfriend talks to you about some amazing feat by another guy, you can say “wow, that’s impressive,” but don’t backlash (it’ll only make you seem jealous), and don’t tumble backwards in amazement either.
(B) Always be driven: Whether it’s in your career or stamp collecting, find a PURPOSE. Be driven, be ambitious, be passionate. Set goals for yourself, both short term and long term. Most people just take life day by day and don’t want to do anything besides find a secure source of income, eat, sleep, and occasionally fuk. This is not you. You want to take over the world; bang Australian super models, become a pokemon master, or the fastest masturbator in the world. Your goals are beyond ordinary, and your enthusiasm for life should awe other people.
(C) Always get out of your comfort zone: I mentioned this a thousand times in other posts, I think it’s a key to working on inner game, and confidence. Confidence is fearlessness, and the more you challenge yourself and overcome your fears, the more confidence you will have.
