Excerpt:

Life is unpredictable, but how you react to challenges determines your happiness and success. The 90/10 Principle reveals that only 10% of life is what happens to you, while 90% is shaped by your reaction. A spilled coffee, a rude comment, or a traffic jam—these events don’t ruin your day; your response does. Instead of letting negativity control you, choose calmness, patience, and positivity. By mastering your reactions, you can reduce stress, strengthen relationships, and transform everyday struggles into opportunities for growth. Apply the 90/10 Principle, and watch how your life changes for the better.
