If given a chance to go back in time...when would that be and why?

It was yesterday during our training class when I asked this question. We had this assessments where we have to write a question on a piece of paper which we have to fold then, one by one, we will pick a question. It was easy for me to think of a question. Maybe because these are the things I think about.

So, if I was the one given a chance to go back in time? when and why?

I should say, I want to go back to the time when I was about to go to College. I would've tried harder to make my dreams and goals come true. I regret entering a relationship while studying. Have I thought of becoming serious in all aspect. May be things would have been better for everyone. Not just for me. Though my life right now is somewhat okay. But, there are things in life I would want to change in case there was such a thing as going back in time.
