Do you really want to do

Confucius said: "If a man is not far-sighted, then suffering will be close to him." Yes, I believe I am closing to belong to the the latter.

I remembered that some body asked me what you were going to be when I was a child. That time, I said I wanted to be a scientist and invent many things.
When I was studying in middle school, I said I could be a scientist or an expert on computer. And when I was an undergraduate, I said I would like to do be a researcher. After I began to study for my master and doctor degree, somebody asked me what I wanted to do after my doctor degree. At this time, I said I did not know. Maybe I would work in a company, or teach in a school, or keep studying on abroad, or nothing. From I was a junior to now; I was very interested in machine learning. Prof. Liu said so I could be a researcher and do some useful research on machine learning and natural language processing. Yes. I think it was a better choice for me.

Yes. I had not any life play of myself. Now, I am twenty-four years old. I must think more about this topic. Maybe a researcher on NLP and Machine learning is better for me.

The most important thing, I think same as others, is do you really want to do.
