21．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．
