This is an evolutionary dead-end. You want to be the OPPOSITE of a sociopath and learn to love, and give into people.
Read "How to Win Friends and Influence People" and "Never Eat Alone". This be selfish crap is both evil, and harmful to your social-standing, not to mention ineffective.
No one is an island, so reach out to people and give as much of yourself to others as you can. Give unconditionally and don't keep score. Empower and inform others, and seek out the same from people. Life is not a zero-sum game: whole of society is better for it when you help just one person.
