“Rules to Live By Remember: Your mind is yours—and yours alone. If you focus on healthy thoughts and develop balanced opinions about your situation, you will cultivate positive emotions and find lasting enthusiasm to live your best life. You will see negativity for what it is: a waste of energy. You will learn to stop allowing fear, anger, and other anxieties to grow. You will discover not only that you can weather challenges, but you often find them enjoyable. As you move in this direction, the work of being yourself will become a joy. To gain all of this, you simply need the right tools and the will to use them.”
