I have learned not to dwell on missed opportunities in my life, from a friend of mine, the late Ed Kretz Jr. He was the son of Iron Man Ed Kretz Sr. who won both the inaugural Daytona 200 and Laconia motorcycle races. Eddy also won a lot of races, when Steve McQueen could not race in the 1965 ISDT he called Eddy to replace him! Now you are asking, what does this have to do with missed opportunities? In 1950, he raced at the Daytona 200, led every lap but the final, when his Indian ran out of oil and seized! I asked if he was bitter over that, he just said, "oh well!" So, other then sickness and death, I don't sweat it any more.
