need break up the stagnancy and self-close

I saw a documentary in which a successful chinese chef was interviewed , when he had the idea of becoming a host in TV program ,which teach people how to cook and how to enjoy the process of cooking , he hadn't lots of experiences , his academic degree not high enough, but he had self-esteem, he pled again and again ,tried and tried , finally he gained the permission and did his job very successfully , and he haven finished many TV programmes after that . he has the natural capacity to make his audience laugh. he attributes his success to his self confidence, he believes that if you are self-esteemed, you will obtain courage, then good ideas and innovation. I enjoy the program very much !
