My life motto is being useful for others. Putting the motto into my head has made me be not a self-oriented person. I used to think self-oriented just like common human beings out there. It comprises thinking about what I will get if I do something for others, what I have achieved compared to others, what I have done to build my reputation, and so on. Consequently, I frequently find myself ending up with frustration and depression when something did not go according to my expectation. Moreover, it was followed by anxiety every night, the afraid of failure in the future. Furthermore, I often compared myself to others. Yet, suddenly short of like negativity has gone since I tried to set my mindset up to be useful for others. Before I went to bed, I barely cared what I've gotten throughout the day. Today, the only thing I care about is what I can do else for others tomorrow.
