If You Were Back In High School What Would You Change

Okay here is a question that I was thinking about for a long time, but just thought I would throw it out there and see if we get a response. Now for all those people out there that are successful or just making ends meet which should be most the world. I was wondering now that your out of school do all the geeks wish they were popular and not so smart but when you answer what would have changed in what you are doing now. On the other hand do all the popular people do you wish that you studied more, and I that too would change what you are doing in life. The last point of view would be well you just like how everything turned out and wish nothing would change.
