Some people say：“it is what you do that defines you”你同意这种观点吗

To be candid,I am eager to confess that I can agree no more about the idea.The first thing I'd like to point out is that those actions one choose to behave just the reflections of their personalities,and that is to say ,one's personality will force someone to be the one they want,not only for his character will have the last word to his future,but also for his ambitions and achievment.There's quite a variety of cases to prove my sayings,like Magret Thatcher,who at last turned out to be the former prime minister of the United Kingdom,she just had the faith that everytime she should be seated at the first row,and that's why she finally became the first woman who had been the British minister for 3 decades.So, you see ,the key point I want to add is that it is actually your thoughts that lead you to do certain business and that's finally defines your future.
