Principles

1. Be professional. When you are at work, you must be professional and efficient. Office is not a place where you have social interaction with others. Instead, it's a place where you solve problems for your boss. Do more and talk less. Finish the works as soon as possible and do your own things.

2. Have a good rest. Do not forget the pain of staying up all night. When you can lay on a cozy bed, you should be thankful and enjoy it even if you cannot fall asleep.
