　　Dear Daughter，

　　As we drove off from Columbia University，I wanted to write a letter to you to tell you all that is on my mind．

　　College will be the most important years in your life．It is in college that you will truly discover what learning is about．I encourage you to be inquisitive，but I also want to tell you："Education is what you have left after all that is taught is forgotten．"What I mean by that is the materials taught isn't as important as you gaining the ability to learn a new subject，and the ability to analyze a new problem．That is really what learning in college is about-this will be the period where you go from teacher-taught to master-inspired，after which you must become a self-learner．So do take each subject seriously，and even if what you learn isn't critical for your life，the skills of learning will be something you cherish forever，so do your best in classes and learn．

　　Take care of yourself and follow your passion in college．Take courses you think you will enjoy．Don't be trapped in what others think or say．

　　Most importantly，make friends and be happy．College friends are often the best in life．Pick a few friends and become really close to them-pick the ones who are genuine and sincere to you．People are not perfect，so as long as they are genuine and sincere，trust them and be good to them．They will give back．This is my secret of success-that I am genuine with people and trust them （unless they do something to lose my trust）．

　　Please treasure your college years-make the best of your free time，become an independent thinker in control of your destiny，be bold to experiment，learn and grow through your successes and challenges．May Columbia become the happiest four years in your life，and may you blossom into just what you dream to be．

　　Love，

　　Dad （& Mom）
