Sometimes I really envy those who dare to do everything, who have no burdens when doing anything, who never look back or hesitate. They just do what they want. If you study their inner world, you'll find that they are filled with a sense of security, so they don't need to seek this feeling from their environment. A person's sense of security comes from within; relying on the environment for security is unreliable—mountains may collapse, after all. Self-growth is the only true source of a person's sense of security. Instead of chasing after external recognition, focus on refining yourself. Inner confidence and composure will come naturally and effortlessly.
