I regret the following:
* Not finishing my Psychology course back in '02
* Not revising as well as I could have done for my school exams
* Selling my limited edition Wrestlemania XX DVD last year
* Waiting too long before asking my Girlfriend out (I could have had an extra year with her and the kids)
* Going through a moody, 'I hate everyone' stage during my teens
What things do you regret doing/not doing in your life?
