#3 Being cocky or pompous
Some guys think they have it all. And at some point, all the attention and the smothering from their parents and buddies make them assume they own the world. They make idiotic statements and love talking about their own glorious deeds or misdeeds. Do you incessantly talk about how well you played a game or how many cars you own?
Well, say what you want, you’re just going to be a cocky pompous prick. Even gold diggers may get bored of you in no time. Learn some humility and you could still get back in a girl’s good books.
