Small shifts in your thinking, and small changes in your energy, can lead to massive alterations of your end result.
Every conscious thought you have, every moment you spend on an idea, is a commitment to be stuck with that idea and with aspects of that level of thinking, for the rest of your life. Spending just 10 seconds focusing on a topic that does not serve your interests is to invest your energy along a path that will continue to draw from you and define you.
