Character determines a person's success or failure, future and destiny. Regardless of good times or bad times, a good character can make people face difficulties calmly, so that they can work tirelessly and achieve success; a bad character can make people hit walls everywhere, suffer setbacks, and even become a huge obstacle to success at critical moments, leading to tragic endings. If you want to change your destiny, you must first change your character. "Changing Your Character Weaknesses" edited by Zhang Yishan takes this as a basis and uses a comparative method to explain the benefits of tolerance, humility, alertness, decisiveness, calmness, caution, tenacity, confidence, boldness and other characters in changing personal destiny. After reading this book, I believe you will have a clearer and more thorough understanding of your own personality, so you can purposefully make up for your character flaws and take control of your own destiny.
