Knowledge and experience

    Knowledge and experience, For a student, Knowledge  may be more important than experience, they should learn more knowledge from their teacher, and broaden eye.
    In my opinion, the practical experience can give us more useful knowledge, because for a graduated student about one year, we should learned from our life and social experience to improve our ability.
    It is said that one learns best by doing.  In fact, I think making mistakes is  the best way to learn. Moreover, if one wants to make new advances, it is necessary to act!
