Feeling that your life is shattered into too many pieces, or that you cannot departmentalize when you choose, is a warning that you are losing control over how you keep aspects of your life separated. Over time, this could create serious psychological problems. If you get married, and your wife or husband has never, ever met anyone from your pool of friends or your work life, the compartmentalizing is getting out of control. If your life, rather than small sections of it, feel like this representation of different feelings and "masks", stop compartmentalizing.  Losing control as stated above leads to either greater efforts at compartmentalization, or great fear of two or more segments of your life ever coming into contact with each other.     It is damaging to open and honest relationships, and raises suspicion in people who are very strictly assigned to one segment or another of your life. Know that you are doing this simply to increase the satisfaction and productivity in life is using this compartmentalization in an effective manner. Although you may not encourage talk of your work life at home, it is neither frightening or “feeling caught” if a family member does ask you directly as to what you do or how your day was. One way to stay in control of your compartmentalizing is not to overbook yourself so that you aren't trying to compartmentalize too many different aspects of your life. Don't get involved in a demanding activity like being the president of the PTA or volunteering to help your friend remodel her entire home if your heart isn't in it. Chances are, that if you're trying to compartmentalize, then you probably have enough going on, so try to minimize commitments whenever you can.  If you're already managing three projects at work, for example, then learn to say no when you're given the opportunity to manage a fourth. Check out your schedule. If you really want to say yes to a new opportunity, see if there's anything that you can cut out of your life.

TL;DR in Chinese:
不要过分地转换角色。 知道什么时候该停止角色转换。 意识到转换角色的目的，及控制方法。 对于根本没必要担任的角色大胆删除。
