Nick Vujicic. Nick Vujicic famously said that every good person has a time of silence. This sentence appears in "Nick Vujicic's Letter to Himself". The original text is "Every outstanding person has a period of silence." During that period, I put in a lot of effort and endured a lot of isolation and loneliness. I didn’t complain or complain, only I knew. And when I talk about it in the future, even I can be moved. Convey the hard work and persistence behind excellence.
