In that a book I'm using as part of my therapy has a set of questions that relate to going back in time.

I'd probably have gone to a different college; realizing now that my High School left me ill-prepared for any top-tier college, likely wouldn't have taken me seven years to finish a 4-year degree.

I also would have majored in Criminal Justice or forensics, instead of Computers. Or just gone to a tech school (ITT, DeVry) and gone into network security.
