Mentor Searching

Just a sweet little short story I had to write for my English class, basically about changing your future, by changing your past. James is a 22 year old college boy who thinks about his past mistakes abundantly, he has a pedantic mother who bothers him on basically every decision on his life. He always thinks how different his life would be if only he did the right things back in his high school days. If you had the opportunity to change your past would you? Might make a side story (20,000+ words) about a certain "later time to continue my 'mentoring'" and being "filled with confidence". If you know my other stories on this site you might know what I'm hinting at.
