Regardless of how you feel inside, always try to look like a winner. Even if you are behind, a sustained look of control and confidence can give you a mental edge that results in victory.
If your message to the universe is gimme, gimme, gimme, the universe's response back to that kind of mentality is exactly the same. The universe will say right back to you over and over again, gimme, gimme, gimme. If you shift that and you say to the universe, to the world, how may I serve? How may I serve? The universe's response back to you is how may I serve you? How may I serve you?
