(True strength comes from within. In other words, it requires you to wake up from your heart. Positive psychology is about effecting change through a systematic approach to action. Establish your own positive psychology system, combined with self-determination theory, systematically understand yourself, understand yourself, and learn to make choices for yourself. People who have achieved self-determination are more aware of what they want and are more daring to pursue it; they also know what they don't want and dare to say no to it. They are more confident, self-loving and secure.)
