Luck
Although it's true that unforeseen events can affect outcomes, it was not luck that made the difference. It was the events. Luck had nothing to do with it.
Believing in luck focuses your thoughts on an imaginary construct that neither you nor anybody else can change or affect.
What's worse, luck is an excuse that explains away failure ("It was just bad luck") and devalues your successes ("It was just good luck").
Enemy
It's true that you have competitors, and that sometimes, for you to win, they have to lose (and vice versa). Even so, there are no enemies in business.
Enemies are opponents in warfare, when people are killing one another. Business is about making things better, not killing people.
The moment you demonize competitors by calling them enemies, you close off your business options. Today's competitors are often tomorrow's partners.
Rejection
Wouldn't it be nice if people always said yes to your ideas? Well, sometimes people aren't going to like your ideas, or even you personally, for that matter.
