3 Rules for a strong Personality

3 rules for a strong personality.
First: Learn to be self-sufficient. Only when you can be happy on your own, you have the ability to say "no" to people who are not good for you.
Second: Never let others drag you into their emotional states. Stay calm, especially in difficult situations.
Third: Learn to read between the lines. Don't just listen to what is being said, but also ask yourself "why" it is being said. By paying close attention, you can understand people's intentions.
