Were you involved in any activities in high school? (Sports, clubs, volunteering, etc.) Are there any interesting projects you've completed on your own? (E.g. do you have a blog?) Do you have any hobbies? Personal qualities to highlight? How do you spend your time?
Rowing for one season, competed in a mathematical modeling competition and didn't win but got a special mention from the judges, traveled to Ecuador for a month as a volunteer project, did some maths and physics tutoring.
Personal projects are pretty limited, but I've got a Django play money prediction market site that I could get running again in a weekend.
Beyond that, there's nothing that leaps to mind.
I think it's past time for another Stupid Questions thread, so here we go.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Please respect people trying to fix any ignorance they might have, rather than mocking that ignorance.
