Motivational Congratulations Speech for Graduation

I am to give a speech at a convocation as the Phi Alpha President, I need a 3 minute long speech and it is to explain what my organization did this semester as well as a brief history, and to also congratulate those who are graduating college this semester. I would like it to be in a motivational context. Include this information: "The purpose of Phi Alpha Honor Society is to provide a closer bond among students of social work and promote humanitarian goals and ideas. Phi Alpha fosters high standards of education for social workers and invites into membership those who have attained excellence in scholarship and achievement in social work." "Through Knowledge the challenge is to serve." "Phi alpha has successfully collected over 600 books for charities in this town. We have had a successful and very eventful semester, holding our banners and morals of our organization high. We could not have done any of this without our members, and it was a great pleasure to work with you all." Please include the information that is listed in quotes, but please don't do it word for word. I would like a motivational speech and the quotes can be shoved in anywhere to make the speech flow better.
