I remember the day I saw Dalai Lama in the Convocation Hall at the University of Toronto.  He was wearing the traditional robe of Tibetan Buddhists like he always does.  And with a humble smile on his face, he started by stating how happy he was to receive a degree without studying for it.  He charmed me with his playful sense of humor and the great compassion he has toward human kind. 
Jane Goodall is the second person that made such a great impression on me.  She is more than just the "chimpanzee lady".  She is a dare dreamer, and the living proof that if you follow your heart, you will get there–the place where you’ve always wanted to be. 
So to all my dear friends, don’t stop dreaming and never stop trying.  We can make a difference if we choose to.
