or but so
I am exceedingly   thankful   to Dr Joan Cook for instilling in me the ability to see myself far beyond what other people   thought of   me.What she said motivated me to follow my dreams   [MASK]   gave me endless strength.Thank Dr Joan Cook,for I   owe   her a great deal in establishing the solid   foundation   of whom I am and for the person whom I am trying to become.Without her it would have been   impossible   for me to become a professor in Harvard University.
