Haw   was    successful   at   last.   But   he   knew   more    things.     He  could   be  more  aware  of  the   need  to   keep   things   simple  ,   be    flexible,    and   more   quickly.    He   always   reminded   himself   to  notice   the    little   change    to   avoid   being   surprised  by   unexpected    change.   He    made   himself     not   be  too    comfortable   to   slip   back.   All   of    things  that   he    had   realized,    he    would   pass   on    to     his   friend    ---  Hem.
