This is a talk by Matthew Richardson sharing his '4 mementos' from BYU in the Spring BYU Magazine. The one I would refer you to is his last one 'You Gotta Believe'. In this story he shares some of the struggles he was having as a student of BYU, his doubts, etc. Then one day he shares a story of a happenstance interaction with Elder Jeffrey and Sis Holland while Elder Holland served as President of BYU. Well worth the time to read.
