I think keeping childlike innocence is not rigid, but a natural expression. Some people are obviously very mature, or very old, but they still pretend to be childlike, which makes people feel disgusting.

On the contrary, some people are old, but they really have a childlike innocence. They are full of positive and optimistic attitude towards life, singing whenever they want, and don't pretend to shirk; Jump if you want, not afraid of being laughed at. The more you do this, the more you make others feel naive. In fact, we saw in TV reports that some old people in their seventies and eighties are still so childlike, which is very enviable.

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.

Although our faces can't shine forever, our hearts are always young, always enthusiastic and always full of passion.
