MY fave time travel story

It's not just a time travel story.  It's about learning a lesson about making a mistake and going back to fix it instead of taking advantage of the ability to make it rich and be hedonistic. 

Then main character does all the above after a major heart attack, and in the end finds out whats most important. I enjoyed the story and the lession he learned in the end about taking material things in life for granted.
