What is the most important lesson you have learned since you had a daughter?

I have learned the preciousness of time from my daughter since I had a daughter. Before I had a daughter, I had a hard time to adjust in USA. I was depressed seriously. I didn\'t live with the joy and peace that God gave me. I complained to God many times because I didn\'t like my circumstances. I walked by myself with my tears around Washington DC for a long time. I felt very lonely. And also, I have lost the meaning of life that God allowed me. Han was very busy at the same time. Every day I\'ve wasted my time without a plan because of depression. However, I realized what is the most important in my life after I gave birth to my daughter. Sometimes I imagine that If I could turn back to the past, I would study hard with passion. Because I don\'t have enough time and physical energy now to study English and counseling. However, I\'m very happier now than mine in the past. Because I got the motivation to grow in life from my daughter. My purpose in life relates to my daughter closely. :)
