Looking for game-changing events in one's life...

I thought this would be a good subject to explore, but little did I realize that it's a loaded program that calls for an impressive number of questions. What are the components of transforming events in a person's life? Education, location, occupation, age, health, accidents, happy and sad events?

Is this all? I have forgotten some other important criteria? Regardless, those points that I have listed are just many important areas that have what it takes to make some impression on all individuals.

Perhaps, I'll take a stab at it tomorrow...
