The third paragraph:


The kind of jobs I would like to work in is persuasive or leadership positions. Public speaking is a good example. A successful public speaker can always catch audiences' attention. I know the techniques about interacting with audiences and that's the reason why my audiences keep paying attention to me. What's more, I like to use my vibrant personity to influence people arround me. Besides, I have a good sense of humour so I am good at creating a good atmosphere by telling some funny jokes and amusing stories. The techniques I know about and the capability which can make the atmosphere more comfortable and surrounding people can be influenced by me easily. With these abilities, I think I can become a good public speaker.
