What do you mean naive?

First of all, there must be a love. Love yourself, love your family, love life, love nature, love everything worthy of love, let everything be beautiful in his eyes, let him get rid of the shackles of the secular, dispel the secular vision, easily find his own life and do what he wants happily. Second, be sincere. Expressing one's feelings sincerely, treating oneself and friends sincerely, less affectation and more true feelings are also a way to keep childlike innocence. Third, be optimistic. Look at life with an optimistic attitude, look at the world with a positive attitude, always maintain an upward passion, and keep yourself young and childlike forever.
