The way you think and feel about yourself, including your beliefs and expectations about what is possible for you, determines everything that happens to you. When you change the quality of your thinking, you change the quality of your life, sometimes instantly.
You have complete control over only one thing in the universe — your thinking! You can decide what you are going to think in any given situation. Your thoughts and feelings determine your actions and determine the results you get. It all starts with your thoughts.
