To stay curious and foolish! We as adults always feel like we have to have the answer to everything and be serious. In my experience when I stay curious and ask questions and allow myself to see the world through a pair of giggly glasses, I reconnect with the feeling of being a kid again. Kids don’t take everything so serious! Also My nephews keep me playful and imaginative ;-)
Being a child again seems freeing in some way, doesn't it?
