"You gotta ask yourself, 'Do you feel lucky?'"

1. Be humble. Part of cultivating luck, writes author and venture capitalist Athony Tjan for Harvard Business Review, is increasing your influence. And the best way to do that is through cultivating something counterintuitive: humility. He added: "People can mistake humility for weakness and avoid it so as not to lose perceived power...You can make more friends in two months by becoming interested in other people than you can in two years by trying to get other people interested in you."
