Speaker: "Snoopy recently turned 50 and like some of us he continues to ignore the worthless saying about old dogs and new tricks. As a re-entry
student I gave up full-time employment to pursue one more dream to obtain
my registered nursing license. After three years at SRJC, I am reaching my
goal. You, too, can dream dreams and work toward any goal. You can become
anything you want to be. There is no end in sight, only opportunities. You
have already reached today's goal and I congratulate you. I wanna encourage
you in the near future to spend some time lying on top of your respective
dog houses dreaming of new dreams and goals for your lives and if nothing
comes to mind or if you feel the slightest doubt or insecurity starting to
creep in just climb down, find your supper dish and celebrate with food,
family, friends, and fun all of your wonderful accomplishments."
