it's not the Chinese way to praise yourself, it is not modest! Who ask you to do so? Any way, to SHOW you have confident, you can say things you are good at. "I'm not afraid of doing somthing", "I am really good at somthing", I believe I can do somthing", "Trust me, I can do somthing", there are just so many ways to convice other people to believe you that you are pretty good.
I believe in myself!我相信我自己。I can do it。我可以,我能行!I never give up。我从不轻言放弃。I am genius。我是天才。I am number one。我是第一 I am the best。我是最好的。I am the man you are looking for。我是你要找得最好人选。I am the guy who can overcome difficulties。我是战胜万难的人。My fate is for ever in my own control。我得命运在我自己的掌握之中。Nothing is difficult for me,if I put my heart into it!只要我努力没有什么对我来说困难的事!Any problems you met cannot be solved,just give me a call!有什么解决不了的问题尽管找我!I am more handsome than Tom Cruise!我比汤姆·克鲁斯还要帅!你的要求对于本来就很难得夸人句子来说又加了一倍的难度,而且夸人应该有个范围的,我不知道该夸什么?
