If you could see your whole life laid out in front of you, would you change things?

I wouldn't...

Nothing?
You wouldn't change the answer that would have given you an a+ instead of an a- on that one test that one time?

@Halcyon: If I got that A+, I'd never know the mistake which led me to A-

I'm assuming you would remember the changes you are making... you did not define that in your initial question.

@Halcyon: I didn't, but I did in my answer

Well then that changes things. No I wouldn't change anything.

@Halcyon: Lol You know you could answer this question in your way of intepretating the question

I gave you both. ;)
