What should I do with award certificates?
Give it to a relative (parent, spouse?). My mother has a "wall of Sergio" in the house where she displays different types of significant awards, letters, etc. I think it's a little weird, but giving them these awards is a nice way to let them have a handy reminder of what you're up to at the time, and parents certainly appreciate it sometimes. My mother and I came from not very much at all, so she is so happy to hear I am doing something with my life -- maybe your family may feel the same.
