"Life really began flowing for me when I finally let go of that ego junk, pride, and feelings of doubt and said to myself, "I'm just going to focus on making the best contribution I can. If I go broke doing that, I go broke. My fears and worries are just not that important compared to the difference I could make if I really gave this life my very best. If I'm here to make a contribution, then the universe had better back me up."
Steve Pavlina

"..getting the focus off the centeredness of your life on the business of serving. The irony of it is that when you get to the point where you're able to do it and let go of that outcome, all of the stuff that you chased after and worked so hard for and figured you had to have, begins to chase after you and show up in your life. You're no longer on the treadmill. It's like a surrendering."
Dr. Wayne W. Dyer

"Financial scarcity is what you attract when you focus on me, me, me — my needs, my problems, my wants. Financial abundance is what you attract when you focus on we, we, we — our needs, our challenges, our potential. The ego is too small a container for wealth."
Steve Pavlina

Covey's interdependence principle comes to mind too.
