I asked myself: why don't you go back to China to visit your parents during this winter break?
I answered: coz I need to work on some important stuff.
Work, work, work. It is always work.
is it worth of it?
I don't know.
The only thing I know is that for someone who is not extremely smart, the only way to survive is to train yourself to live like a machine--You make a plan and stick to your plan and you cannot waste time wondering, feeling, pondering, or, explaining to yourself or others.
Busy work makes you an extremely selfish and self-centered person. (Someone may argue that selfish is different from self-centered, but for now, I don't care about the difference)
You may feel lonely sometimes, but most of the time, you don't even have the time to feel lonely. Work is a greedy monster: you give some, it always asks for more; you give it all you have, it asks you to stay this way and keeps sucking everything from you. If you loss your focus for a second, you are out. Nevertheless, who pushed you to this position of be slaved by work? You and your ambition.
Then maybe you should stop complaining. shup up and go back to work. The one who made the choice must bear with the consequence. It is your own choice.
