"Doing your best is about trusting in yourself and trusting in creation, the force of life. You set a goal and go for it 100 percent without any attachment to attaining it. I encourage you to take responsibility for every decision you make in life. If you practice doing your best, very soon it becomes a habit. When doing your best becomes a habit, everything is a set up for you to always be happy."
